Hello Jeep,

Breck and I have discussed this a little bit off line.

I have a Multi Elmac M1070 power supply that I thought would be usable.  
It would provide my transmitter voltages (500v & 6v). It also provides 
105V regulated via an OB2 which I thought I could use for the receiver 
but the OB2 is rated for 30ma and I'm not keen on pushing the voltage 
that high.  And I would still have to come up with the 1.5v filament.

I found this: http://www.comcents.com/mhrs/theprsup.html
Which looks to be a better solution and cheap enough.  I can even throw 
it into the receiver battery box.

I'm sure I'll be in contact to pick your brain.  Thanks for the offer.

73,
Jon
