Thanks for the replies.
Thankfully it has no IC chips (I cooked one over the weekend
), it has SI transistors throughout. As said, before I go delving too deep I thought I would look at the obvious. If I switch the radio on and put a wet finger on one end of volume pot I get a hum, if I keep my finger on it and move the pot up and down the hum goes up and down in volume as it should thus eliminating any fault with the speaker. The music however goes up and down but still very quiet. If I plug my headphones in and repeat the test the same thing happens through my phones, hum goes up and down in vol as it should and the music goes up and down, however the music is still very quiet. Does that also discount the output stage and the earphone socket? Hope you can understand what I mean. I've also managed to get a tape to play and its no different. I will look around the din socket to the output stage for dry joints etc. as it seems there is a problem between those two.
