Reviews

Hammond 274X Power Transformer
Hammond 274X Power Transformer is rated 4.0 out of 5 by 2.
Rated 4 out of 5 by from Pretty Good for a Fender Clone ProjectI forgot to mention, if I were using EL34's, 6550's, KT88's, etc., I would definitely step up in size (VA rating) as the filament demand of those tubes would push this transformer too far in this case. This transformer would be perfect for a 6V6 project, however the B+ voltage is too high even with a tube rectifier (I tried it anyway) for 6V6's. So pretty much stick with 6L6's with this one.

Rated 4 out of 5 by from Pretty Good for Fender Clone ProjectUsed this as the power trans. for a 1968 Fender Pro Reverb clone project. Very good transformer, good quality. I have it run basically a little more than rated output, 40mA push pull=80mA total idle, (1.5x80mA=120mA, rated output at max musical signal), plus filaments. It is holding up well, runs a bit warm but seems to be very dependable so far.
