VALVE REPLACEMENT AND TROUBLE SHOOTING
Laney
66
TECHNICAL SPECIFICATIONS
SOLUTION 3
Replace the secondary fuse and turn on the power. View the output valves. IF one valve fails to light up, replace that valve.
If the output valves check out OK, another cause of a blown secondary fuse is a damaged preamplifier valve. Start with valve
V1 and replace it. Follow the above procedure. If the symptom persists, consult a qualified engineer, do not fit higher rated
fuses.
SYMPTOM 4
No preamplifier boost
SOLUTION 4
Replace preamplifier tubes V1, V2 or V3 or a combination
SYMPTOM 5
Slow loss of power
SOLUTION 5
Check first for damaged output valves (glowing, flashing or dead) by using the procedures described in solution 3.
All of these trouble shooting procedures can be performed quickly, without the aid of any sophisticated test gear. We suggest
that you always maintain spare valves for emergency purposes. Keep you Laney free of dirt, dust and moisture to prevent
performance failure. Never subject your amp to environmental conditions that would not be comfortable to you!
Should other customer service be necessary, contact your authorised Laney dealer or call Laney service direct.
