Mondial,
Re: checking B+
My line voltage was at 109v from the isolation transformer so I made another set of measurements with full line voltage at 120v. Bias across the 325ohm resistor is 16v. Getting 328 ac volts per plate on the 80 rectifier whereas I was only getting 300 before.

Does sound better and getting a number of stations at this point. Thanks!
