I bought a Leak Delta 30 about 4 years ago on ebay and took it to Japan with me. I didn't think I would use it much but in fact I really like the sound it produces. More than my Quad 303 in fact.
Anyway, one channel has gone down. I have tracked the fault down as far as it being on one of the pre-amp boards because if I swap them over then the other channel dies and the previously dead one comes to life.
The channel is not completely dead but almost. At full volume there is a very weak sound and a bit of hum. I think the sound gradually became distorted and faded away.
Sending the board back to England for repair looks prohibitively expensive as I can buy a working amp for £30 or so and get someone to pull the boards out and post them to me.
However, I would like to fix it if possible. I can solder/unsolder and use a multimeter and there is a circuit diagram here
Can anybody offer any tips? I was thinking of starting with the electrolytics as they are cheap, available locally and are known to fail. Any other thoughts?
