Tranformer Help for Philco Model 90
8/1/2002 6:15:51 PMJoe Miller
I have a Philco model 90 (good set). I found the 1st detector transformer with an open winding. I can't repair it. Anyone know where I can get a replacement (its part number 03015).
I am also thinking of rewinding it but the replacement wire I have is a slightly larger guage. Will it work if I use the same number of turns? The current winding is one level and I may have to overlap it with a few windings of the larger replacement wire. Any tips on rewinding would be appreciated.

Hi Joe

AES, tubesandmore.com and Play Things Of Past, oldradioparts.com should both have replacements.

The following address has a list of coils available from Play Things Of Past.

You could rewind the coil but it has to track with antenna & oscillator coils. Only the secondary is critical. It's part of a tuned circuit. If it isn't close ends of the band won't align properly. The primary is used for coupling and not critical as to number of turns.
