Philco 84 transformer
#3

The schematic linked is the one I found.  Unless I am reading it wrong it shows 8 secondary leads. Two secondaries with a center tap.  My transformer only has 7 secondary leads. 1 center tap.

After doing some more testing, I fear this transformer may be toast.

Findings with 115V applied to primary

1st secondary (no center tap) 5V output
2nd secondary (with center tap). Using center tap, 277V and 278V output .  Without center tap, 598V  output
3rd secondary (no center tap) 107.1V output. I was expecting 6.3

Thoughts on findings would be greatly appreciated.

Thanks.
