Sorry. This really isn't an 18Watt question. However, I figured this Marshall community might be able to help since Drake transformers used to be used in Marshalls.

I've got a AC30 project brewing. Somebody gave me a set of transformers...Drake T-304 (Power) and a Drake T-305 (Output). They're brand new and are apparently used in the Korg reissue Vox AC30s. Unfortunately, I'm having a tough time finding some documentation on how these things are wired up.

Does anybody have a link to, or and idea of how, these things are wired?

Thanks

PhatTele,

Well, I have an idea. MOJO used to distribute these transformers--I bought a pair years ago--along with the choke. Unfortunately, I never wound up using them--and lost them along the way [all the numerous transformers/components/tools I wish I paid more attention to...]. Contact MOJO--they most likely would have a wiring diagram for the taps. If I remember correctly, this Iron had quick connect/disconnect tabs for sheathed terminals.

Good luck.

PhatTele,

...or ask these guys:

I tried both suggestions awhile back. Mojo doesn't have the specs anymore and Drake never got back with me. Someone else suggested contacting Torres Engineering. So, I dropped them a note too, but no repsonse. I'll probably call them.

It's a shame. I'm sure these things work fine. They're essentially new. Unfortuantely, the PT doesn't have the normal black or red leads connected that I'm used to. Just yellow and green. There are lugs for the other connections...just no leads. I have no idea how this thing is configured.

I may just buy some of the "Matchless" transformers from West Labs to get the project going.

Anybody want to buy this Drake set?...I'll sell them cheap...seriously...let me know...jwhanor@mindspring.com

PhatTele,

hope someone comes in who has the required info.

In case nothing else goes..

you have a good base to start from knowing that the trannies are probably for an AC30. Thus, I woudn´t care about the current rating of the windings, the would probably be good for an AC30

Anything else could be done by a couple of measurements.

If you really don´t know where to start, just drop me an email with attached photos.

PhatTele-

Try emailing this guy: David Guesdon "dg@drakepower.com" - he responded to me when I had questions about a Drake transformer and no specs... It may take him a day ro two, but he was quite helpful...

BTW - Hi everybody, I'm new here, tho I've dealt with a few of you already. My name is Dave Nix, tho around here just call me "idiotwithasolderingiron"... It's more accurate.
