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!
