Hey guys...I picked up a small, Yamaha practice amp for my kid...everything works fine...but, the Drive (distortion) really sucks. Can anyone tell, by the pics...which diodes are the clipping ones (D1 & D2...or ZD1 & ZD2)?
Thanx
D1-D2 ,normally they are placed one facing the other in opposite sides to ground
Zd.... are normally zener diode; for voltage regulation.
Hope that helps...
