Congratulations on your purchase of the VINTAGE TUBE SERIES all tube amplifier. Carvin has been building tube guitar amplifiers since 1949. They have been used by top professionals like; Joe Walsh, Chet Atkins, Jeff Beck, James Burton, Jorma Kaukonen, and many other great musicians. You will discover that these amplifiers represent a significant sound improvement over conventional tube amplifiers. Spend time with your new amp and get to know it’s many sounds.
VT16™
OPERATING MANUAL
The T-Bridge passive BASS, MID and TREBLE tone controls offer a wide range of tone settings. Take full advantage by setting them where they sound best. Your sound may not be at center (5 on the dial). Instead, the treble and bass may need to be at 10 while the mid control at 0 (or) the treble at 1 and the bass at 10 depending dual or single coil pickups. The greater range of these controls comes from the high impedance 1 meg sealed pots (most guitar amps use 250k pots). The frequency of the bass control is set at 80 Hz while the mid control is set at 650 Hz. The treble control is set at a very high 11k Hz giving the VINTAGE TUBE SERIES it’s dynamic highs.
REVERB
The FS22 footswitch for the long tailed REVERB system in the VINTAGE TUBE SERIES switches
only the reverb send leaving the tail of the reverb to decay naturally, the way it’s done in the studio. A special pre filter eliminates the spring “boing” normally heard in other systems, giving it a lush sound. The reverb system offers vibrant clarity with full depth reminiscent of the sixties tube amps. (Switching function on 50 watt models only.)
RECEIVING INSPECTION—read before getting started
INSPECT YOUR AMP FOR DAMAGE which may have occurred during shipping. If damage is found, please notify the shipping company and CARVIN immediately. SAVE THE CARTON & ALL PACKING MATERIALS. In the event you have to re-ship your unit, always use the original carton and packing material. This will provide the best possible protection during ship­ment. CARVIN and the shipping company are not liable for any damage caused by improper packing. SAVE YOUR INVOICE. It will be required for warranty service if needed in the future. SHIPMENT SHORTAGE. If you find items missing, they may have been shipped separately. Please allow several days for the rest of your order to arrive before inquiring. RECORD THE SERIAL NUMBER on the enclosed warranty card or below on this manual for your records. Keep your portion of the card and return the portion with your name and comments to us.
GETTING STARTED QUICKLY
FIRST, SET THE REAR 120V/240V AC SWITCH FOR THE PROPER AC VOLTAGE
If you are like most players, you probably want to plug in your new amp and get started playing it right away. You can read the rest of the manual later to learn the finer points of operating your amp. To get started you will need your VINTAGE TUBE SERIES amp, a 120 or 240 AC grounded power outlet, your instrument and a standard guitar cord. If you have the VT16 or VT50 head, you will
also need a speaker and speaker cable. Set the Speaker Ohms switch for the speaker you are using. After checking the rear AC VOLTAGE switch, set Power and Standby switches to OFF and plug into the AC voltage source. Now turn all Volume controls to “0” and set Drive and Tone controls to the “5” center position. If you have the FS22 foot switch (50-watt models), plug into the rear foot switch jack for switching the channels and reverb. Note: The channel SELECT switch must be selected for channel 1 for the FS22 to function. Now, turn the POWER switch ON and allow a few minutes for the tubes to warm up. For 50-watt models, turn on the STANDBY switch. Gradually raise the Volume control, adjust the Drive and Tone Controls and you are ready to go. If you feel your amp is malfunctioning turn the Power OFF and check all connections and settings. Occasionally tubes are damaged or loosened in shipping.
TECHNICAL DESIGN OF THE VINTAGE TUBE SERIES
The VINTAGE TUBE SERIES has a 100% tube signal path - no IC’s, FET’s or transistors. The design criteria was to build an all-tube guitar amp that sounded better than anything else on the market. This meant that the VINTAGE TUBE SERIES was going to be totally new from the ground up and that it was going to be an all tube design.
DYNAMIC EL84 POWER TUBES
Premium EL84 power tubes are selected for their excellent saturation and power soak charac­teristics delivering a tight bottom and soft drive with superior definition.
HIGH IMPEDANCE GUITAR INPUT
Carvin has long known about the effects of miss-loading a guitar pickup which can cause high frequency loss. The VINTAGE TUBE SERIES guards against this loss with its ultra high input impedance. Also, we considered the capacitance of the average shielded guitar cable which can reduce the high frequency response of your guitar pickups. Unlike other amplifiers, we purposely avoided adding capacitance anywhere in the preamp to control high frequency oscillations. Instead, we controlled oscillations through careful component layout and lead placement allowing its shimmering highs to be reproduced.
CLEAN AND SOAK CHANNELS
The equalization of the clean and soak channels is designed to offer clarity to your instrument. Special mud-cutting circuits reduce levels in the 500 to 700 Hz range which normally cause loss of tone defintion. You will also take notice of the clean channel rear PRESENCE control (50w models) which adds acoustic voicing to your instrument. This control boosts only the guitar’s very highest harmonics which are in the 10kHz range instead of the normal 3K Hz of a bright switch.

VINTAGE TUBE SERIES FRONT & REAR PANEL CONTROLS
FRONT PANEL
1. GUITAR INPUT
A standard 1/4” input jack feeds both channels through using the SELECT channel switch. Use a professional quality guitar cord no longer than 25 feet. Typical cable capacitance should be under 50pf - the longer the cord, the greater the capacitance (you can measure this with a capacitance meter). A long cable with high capacitance will reduce the overall treble response from your pickups.
2. CHANNEL SELECT
Set the channel SELECT switch to the desired channel. Channel 1 is designed for clean playing while channel 2 is designed for overdrive/sustain. For the FS22 foot switch to function, set the channel 2 SELECT switch to the channel 1 position.
VT50, BEL AIR & NOMAD
Set AC Voltage switch before plugging in.

8. MASTER REVERB
Set the REVERB control for the desired amount (this works in both channels).
9. POWER INDICATOR LIGHT
As the amp is turned on, the red pilot light will illuminate.
13 15 16 17
14. EFFECTS LOOP
For the lowest possible noise from an effects processor, use the effects loop instead of plugging the guitar into the effects and then into the amp. To use the EFFECTS LOOP, plug the INPUT of your effects into the SEND jack and the OUTPUT of your effects into the RETURN jack. Use shielded cables, not speaker cables. It is normal to have a slight gain reduction of several dB with some effects units. However, the amp has plenty of gain to overcome any loss.
15. FS22 FOOTSWITCH
Most foot pedals with 2 switches, a stereo cord and plug will work. However, Carvin’s FS22 is rec­ommended because of the correct identification label on the foot switch. First, the channel SELECT switch on the front panel must be selected to channel 1 before the footswitch will work. Now that you are connected correctly, the channels and reverb can be switched remotely. If a hum is heard in the speakers, the select switch is in the wrong position.
17. SPEAKER IMPEDANCE SWITCH
The IMPEDANCE SWITCH offers the selection of 4, 8 or 16 ohms to match your speaker system. On the VT16 and Vintage16 the selection is 8 or 16 ohms, or Silent Mode. For the Nomad or Bel Air combos the standard setting is 8 ohms. In the case of adding an extension cabinet, set the impedance switch to 4 ohms. The SILENT MODE setting on the VT16 and Vintage 16 allows you to operate your tube amp without connnecting a speaker. To hear your Vintage Tube sound, connect the LINE OUT jack to a mixer for controlled live sound or recording.
18. SPEAKER JACKS
Two 1/4” SPEAKER JACKS are featured to operate several speaker systems at the same time. Move the IMPEDANCE SWITCH to the correct setting.
19. POWER MODE (Vintage 16™ only)
16. VOICED LINE OUT
The LINE OUT 1/4” jack is “CABINET VOICED” to prevent excessive bass or highs going to your mixer. This greatly aids in sound quality because you do not have to move your mixer EQ setting to the extreme. The 1.5 VAC output (reference to 50 watts output at 8 ohms) is more than adequate to drive any professional mixer or power amp.
Shut the amp OFF before switching between NORMAL (pentode) 16W and TRIODE 5W modes. The TRIODE 5W mode will allow more harmonics to be produced by the power amp and acheive saturation at lower levels.
HELP SECTION
a) FEEDBACK FROM THE LEAD CHANNEL
The VINTAGE TUBE SERIES may feedback if the VOLUME, SOAK, TREBLE and PRESENCE are turned all the way up. Like other high gain tube amps, this is normal. To help reduce feedback and noise, lower the SOAK control to around 5 or 7. Some of the best lead saturation may be found at around 6 instead of 10. Sometimes replacing V1 (12AX7A) can help reduce micrphonics.
b) TUBE REPLACEMENT GUIDE
It is not uncommon for tubes to malfunction during shipping. If your amp is not working properly, first check all connections and settings and refer to the following tube replacement guide.
1) The 12AX7A preamp tubes are the smaller of the 2 types and are located in the following order
982 531 6 74
14
18
on 50w models: V1, V2, V3, V4. On 16w models these are V1 and V2.
To start with, V1 is located closest to the input jack. It is recommended to turn your amp upside
down to replace tubes. All tubes are keyed in the same direction. Replacing V1 (and/or V2 on 50w models) may help reduce feedback due to microphonics. If the power amp is not functioning, check or replace the power amp driver (16w models = V2,
50w models = V4) Check V4 by inserting a signal into the Effects RETURN jack. If the power amp
still does not work, replace the EL84 power tubes.
2) The EL84 power tubes are located in the following order on 50w models: V5, V6, V7, V8. On 16w models, these are V3 and V4. Normally you’ll want to replace these tubes as a set.
Sometimes you can spot defective power tubes when they are glowing red-hot along with an
audible hum in the speaker when the amp is idling. If this happens, shut the amp down immediately.
After the tubes have cooled down, carefully pull straight out to remove. It is recommended to
turn your amp upside down to replace tubes. All tubes are keyed in the same direction. Running
defective power tubes could damage the amp. It is recommended that you have a spare set of
EL84 power tubes along with several 12AX7A preamp tubes.
CLEAN CHANNEL 1
3. CLEAN VOLUME 1
Use channel 1 for clean playing. Thanks to special mud-cutting circuits that work between the frequencies of 500 and 700 Hz, your guitar tones will be full and vibrant.
4. CLEAN - BASS, MID & TREBLE CONTROLS
You can start at 5 on the dial for each of the tone controls. However, these settings do not represent a normalized (flat) sound. You need to set them where they sound best! Most musicians like to reduce the MID’S between 1 and 4 for deeper bass and crisper highs. If your sound is too bright with single coil pickups, you may want to keep the rear PRESENCE control off.
LEAD CHANNEL 2
5. SOAK & 6. LEAD VOLUME 2
To get the Vintage overdrive, keep the VOLUME 2 (VOLUME for Vintage 16™) down until you have determined your final gain level - think of this control as a master volume. Turn the SOAK control up until you get the amount of overdrive you’re looking for. The setting will vary for the same amount of overdrive depending on the pickups used - single or dual coil and the setting of your guitar. The Vintage 16™ low wattage allows you to turn up both controls to get different distortions.
7. LEAD - BASS, MID & TREBLE
To start off with, set the BASS, MID & TREBLE controls at their center (5) position. These controls can set to personal taste or according to the type of pickups used (dual or single coil). It is normal to decrease the BASS at higher playing levels.
REAR PANEL
10. AC POWER & 120/240 VAC SWITCH
IT IS VERY IMPORTANT TO VERIFY THE PROPER SETTING BEFORE PLUGGING IN THE AMP. The rear 120VAC / 240VAC switch must be set for the voltage in your area. An improper setting may cause a blown fuse or irreversible damage. Make sure the cord is securely inserted into the back of the unit. Plug the cord into a grounded “3 prong” power source. No attempt should ever be made to defeat or use the amp without the ground connected. The fuse is located within the AC power cord receptacle. To check or replace the fuse, remove the power cord, place a screwdriver under the “FUSE” cap and pull the fuse holder out. The fuse type is a 250V Slow Blow SB 5x20mm rated at 3A for 50W models and 1A for 16W models. Do not use fast acting fuses, only a SLOW BLOW (SB) type fuse will work.
11. POWER SWITCH
The POWER SWITCH is to be utilized as the master ON/OFF switch. The front panel jewel light will illuminate when the amp is switched on. (The power switch is on the front of the Vintage 16™.)
12. STANDBY SWITCH
Use the rear STANDBY SWITCH If you are taking a break. This turns the high voltage off, increasing the life of your power tubes while keeping the power and preamp tube filaments on for immediate use.
13. ACOUSTIC PRESENCE
The rear ACOUSTIC PRESENCE control adds a sibilance to the high frequencies of your guitar. Most presence controls work in the 3k to 4k range. However, the VINTAGE TUBE’s presence starts at a very high 8k Hz delivering 10 dB at 12k Hz and continues to 20k Hz which extends all the upper harmonics of your guitar. The amount of sibilance will depend on the speakers used. To keep both channels totally independent, the ACOUSTIC PRESENCE is switched by relay only into clean channel
1. The effect of the ACOUSTIC PRESENCE will seem ever so slight, however, the result is added sibilance only to the ultra-high frequencies.
