Roland JC60 with LE Series 2 BJT

 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.
