where to find power transformers?

[joshdfrazier]

so, i'm building a few clones of a single ended Epiphone 101 tube amp from the early 60's. It's only rated at about 5 watts. power and output transformer are both relatively small. having a hard time locating an equivalent power transformer. the secondary has two 550v leads, two 6.3 for the heaters and a ground. any idea where i could find a few of these??

also, the output transformer has only two leads on the primary and secondary. having a hard time finding like OT's as well..

Won't a champ ot work

You might check edcor for a pt

Check out http://www.musicalpowersupplies.com/products/. I've never used their iron but haven't heard anything negative either. They have a 275-0-275 PT that could work for you, and a few SE OT. Their OTs have more than 2 wires each side, but that's because they provide choices for primaries and secondaries. Just heat shrink and tuck what you don't use. Like cbass said a champ set should work. Here's another PT that's 550CT http://triodeelectronics.com/40-18085.html

I can vouch for MPS. For the price you can't beat it. IMHO, the 275-0-275 is too much voltage. I think you'll be better with 225-0-225 (550 total) MC transformer from Triode.

MPS has the OT8-SE output transformer with muti-tapped secondaries, but I think the 8W rating may actually be too high for what you are seeking. It will work fine, but may or may not color the tone to your liking. You'd have to pay to play.

The MC is probably a more conventional choice and offers 4 & 8 ohm output

ok, i was a bit off in my initial post. the PT is actually 250-0-250, for a total of 500v. edcor seems to have the best match/deal of all mentioned in this thread:

it also looks great! I will probably go for the triode 5w champ style OT. seems close enough to what I have currently. I also have a larger single ended OT from a hammond organ amplifier that I'll try out for fun.

phil, i live in baltimore too, small world!
