296 power transformer ?
#1

My power transformer let its smoke out. Previous restorer didn't replace the caps in the condenser block. Doing that now. My question is the original trans is a 3752T and the one I found is a 3752J it is taller and a little wider but will bolt in. Are these the same despite the physical difference? Same tab set up.
#2

The 1936 parts catalog doesn't list any suffix after the number. If the core size is the same I would use it. The power transformers w/2.5 v heater windings are not  very plentiful these days.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!

that's the thing, same part number but my book also shows no suffix. it is larger. Don't know how  to post a pic of them

The letter suffix and size difference may be a 50-60 cycle transformer and a 25-40 cycle transformer. You can use it; you just may need to adjust the size of the filter capacitors. I'll look it up for you...

Thanks. The trans I have is 60 Cycle part #3752 according to my parts book. The 25 Cycle is a different part number 3753
#6

According to the "Complete Replacement Parts List" , Bulletin #39, the 3752 is indeed the 60 cycle transformer, but no suffix listed. I'd say it may be a different run of transformer, and there may have been an adjustment in the manufacturing process, or they used a different form shared with another transformer they were now producing. Should work fine.

Thank you. Was thinking it was an earlier version. the the T versus the J suffix. going to install.
#8

I may be wrong, but I believe T = Thordarson and J = Jefferson. While Philco made a lot of their own parts, I don't think they made their own power transformers. At least not early on.
