Yep, but damn that Admiral transformer is the right one!!!
B+ levels off at 285, and everything's looking good! I'll just make a socket adapter for the top of the transformer and wire it in to the 5U4 socket underneath.
NOW!! Here's the problem. This thing hums so loud it howls!
The filter caps it called for were two 40 uF @ 475V....someone did a sloppy job of sticking in two pair of 22 uF @ 400, so I replaced them. But the damn thing just howls so loud that I can't tell if I'm getting any stations!
Possibly the filter choke? Spec says it's 17 henries, but I have no idea how to measure that....and no idea what beyond a filter cap would cause that hum. Damn well sounds just like a bad filter cap too.....
