Hoho
I have a very nice solid state amp made in 1981. It is a Roland Spirit and although I am am dedicated tube man I must say that this is one fine amp. Im having hard time finding diagram/schematic for it. Can anyone help me there.
Merry Christmas to you all

What isn't working? If a Roland is working well, you probably don't want to go inside.

> It is a Roland Spirit

There were at least three models.... the model number may be helpful?

Hi PRR. Its a Spirit 30 and its working fine. I am just interested to find out why this one sounds so fine, even breaks up like a tube amp at higher volumes!

Nothing exotic or erotic. Good 1980s Japanese design. A lot like an oversize effects pedal.

DO NOT SHORT THE OUTPUT!! There is NO protection for the power transistors.

Input amp is NFET-PNP working from quite high voltages. Volume pot, and clipping diodes with high part-numbers suggesting a late revision. NFET buffer. Fender-like tonestack. Tone recovery with another NFET-PNP pair. More clipper diodes. Reverb feed, NPN buffer, reverb mix, power amp.

Spirit 30 and Spirit 50 differ in supply voltages, appropriate gain change, and frills. The 50 has overdrive knob and Pre-Out Main-In jacks. The connections are on the PCB, just not used on the 30.

I got the manual from the link above:
