Thank you for choosing the Traynor YBA200 All-Tube Bass Amplifier. You are about to revisit one of the best
quality-of-sound instrument amplifiers ever built.

The YBA200 is truly an evolution of technology. In true Traynor all tube tradition, no semiconductors are in the
signal path and features like a Resonance control adjusts the damping factor at the amplifier’s output stage (allowing
the player to take full advantage of the tonal capabilities of instrument speaker cabinets). Modern technologies, such
as specially designed toroidal transformers, allow increased reliability and real vintage tube sound, unheard of in
modern tube amplifiers. The YBA200 has real vintage tube sound, no compromises, no excuses.

Features

• Two 12AX7 pre-amp tubes, a 12AU7 phase-splitter, and four 6550 power output tubes
staying true to the All-Tube Signal Path Traynor philosophy. Class A/B amplification.

• Variable-range 3-band passive tone stack EQ with Scoop and Resonance Controls

• Unity gain, balanced DI output. Selectable Pre-EQ or Post-EQ, –20 dB pad and Ground
Lift.

• Pre-Amp Out and Power Amp Input jacks. These jacks are capable
of acting as a pre-amp, a slave amplifier or an effects loop (for
professional-grade signal processing equipment).

• Tuner Out jack and Mute switch.

• Extremely lightweight due to specially designed toroidal
transformers and technology optimization.

Due to the nature of vacuum tubes, it’s suggested to
power up the YBA200 for a few minutes prior to using.
This will allow the tubes to warm up. The pilot light
glows red when the amplifier is engaged, an amber

glow signifies the Standby mode.

Note: Before powering up and disengaging the Standby switch
make sure speaker cabinets are connected to the output jacks.

When the amplifier is warmed up, disengage the
Standby switch and get ready to experience the classic
tone of a Traynor Bassmaster All-Tube Amplifier.

Note: It’s also recommended to leave the amplifier
powered up during set breaks, The Standby switch cuts all
outputs from the preamp and power amplifier.

2. Input Jacks

The YBA200 is equipped with 2 input jacks. The 0
dB input feeds the first tube input-stage directly while

the –6 dB input applies a pad to it. The –6 dB input is
usually used for bass guitars that have active pickups, or
extremely hot levels.

3. Tuner Output & Mute

The YBA200 features a ¼-inch Tuner Output jack to
enable direct connection with a tuner without affecting
the signal path into your amplifier. When the switch is
depressed the Tuner Out jack receives signal while
the power amplifier and the DI Output are muted. This
allows you to tune your instrument without affecting the
sound going to the speaker cabinet, control board or PA.

4. Gain Control

The Gain control is placed just after the first tube­stage and is used in conjunction with the Master

volume control to help achieve the proper sound and

feel. This control also allows the capability of giving a
warm overdriven tube sound when turned up (even at
low volume levels).

5. 3-Band Equalization and Range Control

The YBA200 features a vintage passive tone stack
consisting of traditional Treble, Bass and Mid
Controls. Additionally, the tone stack is equipped with
a Range control; this adjusts the frequency range for
the Treble, Bass and Mid controls.

6. Bright Switch

The Bright switch provides a small amount of treble
boost for added presence.

7. Scoop Switch & Control

The YBA200 is equipped with a defeatable Scoop
control to help accentuate deep bass and treble
frequencies. Maximum midrange scoop is achieved by
turning the control fully clockwise.

8. Resonance Control

The Resonance control is placed on the output stage
of the power amplifier and controls the amount of
low frequency damping. Setting the control clockwise
reduces the damping factor and allows the resonance
of the speaker cabinet to be more pronounced.

Note: Setting the control counter-clockwise will increase
the damping factor and produce a tighter sound.

9. Master Volume

The Master control adjusts the overall output
level of the amplifier. The level being sent to the
Balanced Line Output is not affected allowing the
signal at the mixing console to be unaffected by
adjustments during performance.

The Pre-Amp Out and the Power Amp Input jacks
provide versatility not usually associated with vintage
tube amplifiers. The Pre-Amp Out jack can be used
to slave another YBA200 or as an effects send. The
Power Amp Input goes directly to the YBA200s
amplifier, bypassing the pre-amp, which allows a
perfect effects return. The Power Amp Input also let
the YBA200 be a true slave from another pre-amp.

Note: The output signal of the Pre-Amp Out is set at 0
VU. When using the Pre-Amp Out as an effects loop it’s
recommended to use professional-grade signal processing
equipment (pedal effects might not have enough headroom).

11. Balanced Line Out (DI Output)

The YBA200 is equipped with a unity gain, balanced
DI output. You can select a direct, clean signal (Pre­EQ setting which delivers the sound directly to the
Balanced Line Out) or tap the signal after the pre-amp
(Post-EQ). Both signals are routed to the Balanced
Line Out before the Master volume. A Ground Lift

(lifts Pin 1 of the XLR) and –20 dB attenuation switch
are also provided to help when routing signals directly
to other equipment or mixing consoles.

12. Speaker Impedance Switch & Speaker Outputs

Extension speaker cabinets are connected using the
Speaker output jacks. Connections to these jacks are in
parallel. Using the Speaker Load switch, the output of
the YBA200 can be optimized to provide the rated full
power (200 watts) for selected loads (8-ohms or 4-ohms).

Note: As long as the total speaker load is not lower than
2-ohms, Speaker Load settings of 4-ohms or 8-ohms are
interchangeable. Choose the setting that sounds best to you.

13. Replacement Tube Selection & Bias

This amplifier features Yorkville’s auto-balancing /
auto-matching tube biasing technology. As a result,

when the time comes to replace the tubes in your
Yorkville amplifier, there is no need to pay a premium
for a matched set – nor does the bias need to be
adjusted when you use a different brand. We make
no claims as to which brands of tubes might sound
best, but with auto-balancing / auto-matching, you
are free to experiment without any need for concern
that the amplifier or tubes will be distressed. Please
note that auto-balancing / auto matching cannot fully
compensate for different types of tubes - 6L6/5881s
versus 6CA7/EL34s, for example.

Please note that although auto-balancing / auto matching
allows you the freedom to select unmatched tubes from
a variety of manufacturers, it may not be able to fully
compensate for the use of a non-equivalent model or
part number of tube – 6L6/5881s versus 6CA7/EL34s,
for example. Use of non-equivalent tubes may result in
unpredictable performance.
