Steve,

Before you proceed, do check tubes, check transformer with rectifier tube removed, check tubes,  especially rectifiers, electrolytics polarity, and short after rectifier and across all filaments.

Great advice   Tubes are all new and tested (the old tubes were only half present, and I'm not re-using the 36 or the 6-series tube someone had installed in place of the 75 so I needed to get new ones for those and the missing ones - and I got a good deal on a complete set).  The original rectifier (80) tested ok in my tester - but its not the most reliable piece of equipment I own... and the transformer tested ok on the bench - but it has yet to have power through it.  I avoided testing it because this way I will be motivated to rewind (or have it rewound) if it needs it.  There was a lot of wax around the wiring so its been warm in the past... We will see...

You've just made me second-guess myself about the electrolytics... I may pull them out now to double check

And checking for a short on the filaments is a good idea... I'll do that too since I'm reusing the original wire and it runs all along the chassis edge.
