Budda SD18 Musical Instrument Amplifier User Manual


 
Trouble Shooting Tips:
Preamp and power tubes may become microphonic and lose power over time. A
few of the common symptoms are:
x A high-pitched squealing sound when you turn on your amp.
x A static sound when your guitar volume is turned down.
x A loss of output or a muddy signal.
One simple test to determine whether your amp is experiencing preamp or power
tube problems can be performed by plugging your guitar into the effects return of
your amp:
x If the static or squealing noise continues, then the problem is related to the
power tubes or driver tube (third from left) and they should be replaced.
x If the static noise goes away, then the first or second preamp tube is the culprit
and should be changed. Start by replacing the first position tube, farthest to the
left looking at the rear of your amp.
We suggest changing power tubes every 6 months for those who play their amp
more than an hour per day 3 to 5 times a week. You can get a copy of our tube
layout chart online at www.budda.com (click on Resources).
