Hi Guys.....
On the bench as I write is the power transformer of a Philco 630. The original transformer has died and went to flux heaven. The replacement, a known good transformer (so far), needed the usual new extension leads and a trip to the painting booth.
What I need to know before installation is the idle current draw on the AC primary side of the transformer. Hooked up at 117 VAC, I'm seeing a draw of 160 ma. (+/- 10 ma.)
Is this number in the ballpark? Unlike new transformers, I know the efficiencies of these older units can vary quite a bit and before I go about installing this one, I'd like to get a handle on whether or not the transformer will be a good candidate.

All ruminations welcome...
...Jim
