2.The product should be powered by a three pin `grounded (or earthed) plug connected to a power socket with a grounded earth outlet.
3.All safety and operating instructions should be retained for future reference
4.Obey all cautions in the Operating instructions and on the back of the unit
5.All operating instructions should be followed
6.This product should not be used near water, i.e. a bathtub, sink, swimming pool, wet basement, etc.
7.This product should be located so that its position does not interfere with its proper ventilation. It should not be placed flat against a wall or placed in a built up enclosure that
will impede the flow of cooling air.
8. This product should not be placed near a source of heat such as stove, radiator, or another heat producing amplifier.
9.Connect only to a power supply of the type marker on the unit adjacent to the power supply cord.
10.Never break off the ground pin on a power supply cord.
11.Power supply cords should always be handled carefully. Never walk or place equipment on power supply cords. Periodically check cords for cuts or signs of stress, especially at the plug and the point where the chord exits the unit.
12.The power supply cord should be unplugged when the unit is to be unused for long periods of time.
13.If this product is to be mounted in an equipment rack, rear support should be provided.
14.The user should allow easy access to any mains plug, mains coupler and mains switch used in conjunction with this unit thus making it readily operable.
15.Metal parts can be cleaned with a damp cloth. The vinyl covering used on some units can be cleaned with a damp cloth or ammonia based household cleaner if necessary. Disconnect the unit from the power supply before cleaning.
16.Care should be taken so that objects do not fall and liquids are not spilled into the unit through any ventilation holes or openings. On no account place drinks on the unit.
17.A qualified service technician should check the unit if:
!The power cord has been damaged
!Anything has fallen or spilled into the unit
!The unit does not appear to operate correctly
!The unit has been dropped or the enclosure damaged.
18.The user should not attempt to service the equipment. All service work is done by a qualified service technician.
19.Exposure to extremely high noise levels may cause a permanent hearing gloss. Individuals vary considerably in susceptibility to noise induced hearing loss, but nearly everyone
will lose some hearing if exposed to sufficiently intense noise for a sufficient time. The U.S. Government's Occupational Safety and Health Administration (OSHA) has specified the following permissible noise level exposure.
Duration Per Day In Hours |
Sound Level dBA, slow response |
8 |
90 |
6 |
92 |
4 |
95 |
3 |
97 |
2 |
100 |
1 ½ |
102 |

¼ or less |
115 |
According to OSHA, any exposure in excess of the above permissible limits could result in some hearing loss. Ear plugs or protectors in the ear canals or over the ears must be worn when operating this amplification system in order to prevent a permanent hearing loss if exposure exceeds the limits set forth above. To ensure against potentially dangerous exposure to high sound pressure levels it is recommended that all persons exposed to equipment capable of producing high sound pressure levels such as this amplification system be protected by hearing protectors while this unit is in operation.

OPERATING INSTRUCTIONS
BEFORE SWITCHING ON
After unpacking your amplifier check that it is factory fitted with a three pin 'grounded' (or earthed) plug. Before plugging into the power supply ensure you are connecting to a grounded earth outlet.
If you should wish to change the factory fitted plug yourself,ensure that the wiring convention applicable to the country where the amplifier is to be used is strictly conformed to. As an example in the United Kingdom the cable colour code for connections are as follows.
EARTH OR GROUND - GREEN/YELLOW
NEUTRAL - BLUE
LIVE - BROWN
NOTE
This manual has been written for easy access of information. The front and rear panels are graphically illustrated, with each control and feature numbered. For a description of the function of each control feature, simply check the number with the explanations adjacent to each panel.
Your Laney amplifier has undergone a thorough two stage, pre-delivery inspection, involving actual play testing.
When you first receive your Laney guitar amplifier, follow these simple procedures:
(i) Ensure that the amplifier is the correct voltage for the country it is to be used in.
ii)Connect your instrument with a high quality shielded instrument cable. You have probably spent considerable money on your amplifier and guitar - don’t use poor quality cable it won’t do your gear justice.
Please retain your original carton and packaging so in the unlikely event that some time in the future your amplifier should require servicing you will be able to return it to your dealer securely packed.
Care of your Laney amplifier will prolong it's life.....and yours!

OPERATING INSTRUCTIONS
Dear Player,
Thank you very much for purchasing your new Laney product and becoming part of the worldwide Laney family. Each and every Laney unit is designed and built with the utmost attention to care and detail, so I trust yours will give you many years of enjoyment.
Laney products have a heritage which stretches back to 1967 when I first began building valve amplifiers in my parent’s garage. Since then we have moved on from strength to strength developing an extensive range of guitar, bass, public address and keyboard amplification products along with a list of Laney endorsees that includes some of the world’s most famous and respected musicians. At the same time we believe we have not lost sight of the reason Laney was founded in the first place - a dedication to building great sounding amplification for working musicians.
Warm Regards,
Lyndon Laney CEO
INTRODUCTION
The Dark Art: In an age where guitar players have developed an unhealthy fascination with pre-amp distortion, the fabled sound of a tube power amp being pushed hard has almost passed into history. Until now that is!
The L20H’s hand wired 20W Class A Single Ended output stage oozes classic, warm tube tones: The harder you drive it, the better it sounds. Plus with enough gain for contemporary tones, it also has a mean, spiteful side to it as well – making it ideal for any style of playing. Perfect for studio and practice use, but also equally at home or on stage plugged into a Laney LT-212 cabinet, the sound will blow you away. The L20H can be secured to the LT-212 Cabinet using the optional fitting kit.
Every Lionheart product is extensively play tested by experienced guitarists before being shipped to our customers. Only when the unit is finished to our complete satisfaction is it assigned its own unique build number which is then hand stamped onto the rear mounted plaque.
Your L20H’s should give you years of trouble-free amplification, however please take time to read this manual and familiarise yourself with the controls as it will allow you to get the best from your amplifier.We hope you enjoy using your L20H’s as much as we enjoyed designing and making it.
Best wishes from all at Laney
