The transistors do not make it sing and secondly, they did not make enough gain - the JCM 900 is NOT high gain, but a medium gain. They corrected this later with the ensuing SLX model by adding one more valve. (ps. I am saying transistors but they might be diodes etc.. I am not a technician).

Brett, I think the transisitors you are referring to are actually are clipping diodes. The SL-X doesn't use them for distortion as it has the 4th preamp tube for that (super high gain). I may be wrong but I think there are no diodes at all in the SL-X except possibly in the effects loop for other reasons than distortion........
