Pye Black Box

 

Here's the underside of the amplifier after repair. One weakness often found in early BBs is that one of the transformers tends to fail, and that's expensive to put right. Happily, this machine didn't suffer from that. I did have to replace the main smoothing capacitor - which was a pain to do tidily, but I did it - and a few other capacitors as well as replacing the mains lead with a new one, properly anchored rather than just knotted! The controls have all been checked and cleaned to ensure smooth and silent operation, its all working perfectly, and it's ready to go back in the box.
