Amplifier Discussion / Converting audio amp to guitar amp
« on: April 06, 2010, 04:40:58 PM »
hi i have a audio poweramp that i would like to convert into a guitar power amp and add a preamp, maybe tube based.
well the amp right now is a Yamaha A-320 the transistors are: SK A1104 and SK C2579, i have found a datasheet on the last one its a NPN, my guess is that the first i PNP and its push-pull amp.
i was thinking that maybe its that simple as to put a preamp before the volumepot, would be nice but propably not.
so... has any onemade a similar convertion or might have an idea that would be usefull.
