[R-390] R-390 fix - prob 1

[John Lawson]

The B+ is supposed to be 180V - at the TP it's more like 120 - 130, and 
the Hum Bal control (that, pre-doc, I thought was a voltage adj) varies 
the B+ by about 20V - and she's humming a lot to boot.

   So - check the PS and AF chassis first - see if something's puked other 
than a Valve.

   But that's tomorrow's project. tonite I'm just reading the docs from 
BAMA.

   Cheers
