Probably lot's of options. I'd start by looking at Hammond's AC-30 transformers.

I have used hammonds with my AC30 and other builds and they seem to my limited opinion to be amazing :)

I have also used the Hammond AC30 power transformer for a 4x EL84 amp I built a while back and it worked great. I used there 290MX.

Thanks guys.

Dave I wrote down the HTS-7042-3 in my quest for 36w iron but they had used HTS-7013-1 OT.

I think there are a few HTS numbers with the same spec :? But I'm sure Phil will know the right one!

Dave,

I didn't notice this before but you wrote down two PT's and no recommended OT?

Hi Mark,

Sorry about that. I believe the 36W OT is HTS-7013-1.

Sure thing Mark. You might want to email Phil or Alden directly? I was speaking to Phil just this morning and he has been getting back to me quickly.

The PT came as a standup which surprised me but I used it anyway. Next time I better advise Heyboer I want it laydown for combo or standup for head.
