Finally it is done! Had to put a new amp module because i cannot restore
 fully the original one (no parts available). Module is a Laguisma 
Series 2 BJT using power transistors with Motorola part numbers 70484140
 and 70474140; transistors that are tailored for Peavey equipment. 
A clean sounding guitar amp with a light overdrive when engage and great sounding spring reverb.
