-B. The info on sheilding is good to know, I'll start with a replacement
OD3, (I have two coming from an ebay supplier) and go from there since I
have no test equiptment. If that fails, I'll look into the power supply
issue. And probably contact the fella I spoke of above who works on tube
radios.

There's nothing wrong with the OD3. Go buy a good multimeter..
