[QUOTE="ludo, post: 81436, member: 691"] Wasn't me. ;D Intriguing design that. The speaker outputs are capacitor coupled and the supply is a single rail. So there must be a bit of a thud as the output cap charges up to 1/2 the supply voltage after switch-on. If the transformers each have single secondaries of 38V or 39V that should be correct. If they are lower, that might cause a bit more thud at switch-on, and maybe some other problems too. But having a toroid made for it will be expensive if it's going to stay in the garage. You might want to tape up that mains fuse holder or replace with a clip on a bit of PCB with some stand-offs. It looks to be of fair quality but I have seen them crack. (The inside is spring-loaded, and plastic is, well, plastic.) There is no chassis earth so if it comes apart that would be dangerous. [/QUOTE]
