TAD 150 Pre Amp transformer died


Hi Everyone,

Local stereo repair shop couldn't find a replacement anywhere.

Any thoughts about getting another power transformer for this pre-amp ?
Guess it's pretty unique.

Thanks...

Here's an email I got from BEZ this morning:

Sorry this pre amplifier is not our product so we can’t repair.

We wish to help you but we only make EI core transformers.

Best regards

Hoping Mercury Magnetics can help.

Thanks so much for the replies Czarivey, Grannyring and Metman.
Any further thoughts please let me know.
No stickers, no specs. Repair shop wrote down 4 numbers he said were important, think they represent voltage.
on the left (incoming): 110
on the right (outgoing): 200 11 32

If you had a choice between Torid vs CI, would you choose one over the other ? (original was torid)

Mercury Mag said they wouldn't make a torid for audio but could probably make a CI that would work.

Hammond might be able to make a torid version.
Sounds like Audcom is no more.
I heard years ago the factory closed (maybe burned down ?).
One dead end after another.
Hate to end up selling this for parts...
I'm in Tampa. The stereo repair shop I took it to
couldn't find anyone that could make a replacement (≤$400 anyway),
as the machinery to make toroid transformers is apparantly very expensive.

As it stands the only option is to send the blown transformer to
Mercury Magnetics and hope they can make a comparable CI version.

But I'm happy to pay you, Grannyring, if you can do it.
Hope you're right, but the search has been nothing but discouraging so far.

Here's the reply from Hammond Mfg:
"Sorry but that would be a custom design very expensive to do but before you ask for a cost I need the amperage for each output voltage."

Is that even possible to calculate from a dead transformer ?
