[Milsurplus] BC-348-R SNAFU

[Laura and Jim]

I repaired the BFO in my rig (new bypass cap and associated resistor), and now it won't even let smoke out! 

While running, the dyno output lugs down to 90V. I pulled the dyno and it appears to be fine when used on another rig (~240V, caps check OK). 

Measuring across B+ and B- leads w/dyno still removed I get 370 ohms in all three switch positions AVC-OFF-MVC (varies by ~0.1 ohm). 

I'm thinking a bypass cap doing this (B+, short to chassis, then from chassis to B- via the output stage audio transformer). Getting the same value in the OFF position suggests this to me. 

Any ideas?
