Input please on 25 cycles radios 1930ish

I'm sure that radio uses a type 80 tube and two type 45's. The 80 will be a little pricey (depending on if you go for an original globe envelope type or one with the newer style envelope) but the 45's are about $80 a pop from AES. You can think the audiophool crowd for that! Be glad they're not made by Western Electric or they'd be $800 each! I usually won't replace a 45 unless it's dead. I've seen plenty that would check "bad" on a tube tester; but, would still perform in the radio. The other tubes should be reasonable.

I think 25 cycle power was used in Canada and I've seen some Sears Silvertone schematics for 25 cycle versions of their normal 60 cycle radios. You may have to replace the power transformer with a 60 cycle transformer; but, let's see what someone else says first. IIRC, that power transformer is encased in tar in that model. So, you'd have to melt out the tar and install a newer transformer in the old case if you expected the radio to look original.
