I have first hand experience of random people contacting me via my website and offering 500euro and up to 1000euro for some of my radios which contain the same amplifier board.
I have finally got to the bottom of how all this started and I totally disapprove of destroying a radio to make a tiny guitar amp.

Its a fad craze not un-similar to the audiophoolery that you hear about. In my view it should not be welcomed on a vintage radio forum.

Most of the components to this amp are freely available. The only issue is the audio output transformer windings are a mystery so people are pulling them out of radios. I've searched most forums only to find the guys that do buy them keep everything a mystery. It'll just take one experienced person to carfully unwind their audio coil and release this info. Plenty of people would be happy with a non genuine circuit board and parts in their guitar amp but it's got to be the correct circuit with feedback. Primary to Secondary winding ratio - Wire Gauge/s - layering of the winds in the correct order.
Im going to have a go at winding a few to see how they sound so any info here would be appreciated. And Im not destroying anything.... apart from a few cheap Chinese transformer for my blanks.
