Aaaaaaaaaaargh, I had an amp from an established company, can't remember this company, everything was connected by wire-wrapping, so indeed a good discrete circuit, but the wire-wrapping did cause defects. Btw. I prefer good old leaded solder, but leaded solder in Germany isn't allowed anymore. We should start to wire-wrap all electronic devices for our politicians here :p. Cheers!
