Philco 45 Warm Power Transformer
#4

At today's line voltages, wouldn't you all say this is normal? It's not too hot to touch, and there isn't any sizzling heard! Icon_smile

I'm not familiar with this radio, but there are a handful of ways to correct the "problem." The easiest, get a variac, and run the radio through it. Or a power resistor could be used - to drop the line voltage. Best method, use a bucking transformer, to do the same.

Search the 'net - you'll find all the info needed!

I've read, on many occasions, if the transformer is "warm" - as explained - it's OK. On the other hand, I've also read on many occasions, your radio will like you better, if you reduce the line voltage. Some claim to reduce incoming to 110 V, and you won't notice a difference.

When I have a radio on the bench, it's run through a variac, with reduced voltage. Once it leaves, it's on it's own!
