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

allowed anymore. We should start to wire-wrap all electronic devices for
our politicians here :p.
