I wired the amp up last night, but got finished too late for a LOUD
listening test ... but so far so good. I did not install the Rfb resistors
yet, I'll evaluate it without, and with one, thanks for the ideas.
I bought some predrilled board and forked turrets and tool to make
tie points. They are mounted on the tube socket hardware with
4/40 3/4" spacers. I cut the board with my Dremel, hence the burned
edges (and fiberglas in my lungs) They work pretty well when there
are lots of tie points. The turrets are made out of really hard metal,
and I tapped them in with a hammer. Maybe I'll get a little 1/2 ton
press, or try using my drill press to squeeze them in.
