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...

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...
No need to sell for parts any good repair place will simply replace the tranny with one spec'd accordingly.

What area to do live? Goodness even I could do this simple job. You can get your pre fixed for sure.
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.
Take Grannyring's advice, The 150 is an excellent pre and you should Be Able to find a competent repair shop to do the work
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 ?
