Which Transformers for low voltage/high current operation?

[bruno]

I'm trying to design an amp around a pair of 6V6s which would work at what I guess would be similar to class A. I'm using the datasheet values as references for a class A push pull tube amp, which point out to 250 volts on the plates and max current of 80ma.

Where could I get a power transformer that and output transformer that would handle these specifications?

Thanks

Look at Hammond Transformer

I've looked at hammonds, they'll do for now, but I'd like to know if you guys knowis any company where I can have these custom made?

If not than I guess I'll go with a heyboer ac15 OT and a hammond 369AX power transformer which appears to have 125V unloaded B+ per side and is spec'd up to 115ma.

thanks

I'd look into Edcor, if you haven't already.  I like their off-the-shelf offerings, and don't have any direct experience with custom orders, but from what I've heard they are pretty easy to work with, at a reasonable cost.

Thanks man, I just checked edcor... they have loads of options, and reasonable prices too. I'm going to order a set!
Thanks

Bruno , you want custom made ? ( $$$) ask Mercury Magnetics

I also recommend Edcor---- they offer many stock PT's and will custom wind---i had some custom wound PT's done several yrs ago and it was a painless experience.
i used an Edcor PT in a recent 50 watt hi-gain/clean channel switcher build (a local studio has "borrowed" it for several weeks--i may have to take it back by force pretty soon--- they seem to like it)---i also have two Edcor PT's on order that would easily support 100 watt channel switching builds:

I may use one of these Edcor PT's in a KT88 x 2 build with one of the custom wound Heyboer 100 watt OT's i had them make up (Heyboer also does great custom work !!!)---- These Heyboer OT's are a Fender Twin Reverb/Showman-type --- but with 4k primary and 4/8/16 ohm output taps---i just did a Bogen CHA33 gut-and-rebuild with one of these Heyboer OT's and a Mag Comp Twin Reverb/Showman PT--- KT88 x 2--- Fender Brownface Deluxe 6G3 based circuit--- holy crap !!!!--- kind of like putting a Big Block 454 into a Chevette !!! I wasn't sure if KT88 x 2 would give "Big Amp Feel" with this transformer set, so i built up this old Bogen as an experiment------ very powerful and has Big Amp Feel----- i also included a PPIMV (LTP PI in this circuit).
i'm sure that Mercury Magnetics can do great custom transformers------ but Edcor and Heyboer can do great custom work at a much lower price......................gldtp99
