Does anyone have schematics for Barcus Berry model 1720? It is 70's-80's acoustic guitar combo. i've been using it for electric guitar and it has great cleans. I've tried to email Barcus Berry but can't get any answer.

I just got cheap KMD solid state amp and tried to find some info of it. Only thing i found was old KMD brochure. It seems that nobody uses them anymore. I found the clean channel quite nice, actually so nice that i'm going to sell my tube amp (i'm mainly using clean channel now so don't need tube distortion). Does anyone here own these amps?
