Big, Bad*s*, and ugly 660L
#25

So I haven't given up on it but a few things have happened since last posted. Started to homebrew a replacement osc coil for the bc band. Did get to oscillate but need to remove some turns as it oscillates too low in frequency. Started with about 110t of 36g wire tapped at 10t for the padder.

Meanwhile I was digging though some loose parts on my workbench in the basement and found a Miller OSC-69 coil. It's a universal replacement coil so I may give it a go to see if it will work in this circuit. It's alot smaller than the one I wound up and would be easier to mount.

The red plate in the rectifier has reared it's ugly head again which is starting to annoy me a lot. B+ was down to 150v or so. This is getting tiring really tiring! But it wasn't the 42 tube it was the tube socket that I replaced, it was arcing though the thin wafer up to the chassis. Found 20 replacement molded sockets for a buck a piece. Should be here by the end of the week. I may do some more work with the coils and just leave the socket disconnected till the replacements get here.

The top coil is the homebrew coil. To put them into perspective it's a 1/2" in diameter the Miller coil is a 1/4"
