Hear is the radio amp I made after watching reddogs videos on line.
I think this is a UK radio make, the conversion was quite easy tapping in behind the volume. I also get the tone knob too !
This is what it sounds like https://www.youtube.com/watch?v=K_KmIWUr11Y
I got a job lot from ebay and this one was working. I changed the battery conection from the existing older 9v one to a new one. I also drilled a hole in the top to mount the jack.
