Who is recommended for repairing or rebuilding audio transformers (Hafler design in particular)?
What is the exact transformer? To help better answer the question.....
It is the LF transformer in an Acoustat MK-121-C Hafler Red Medallion. Interleaved windings, nomex, not sure if it can be repaired or needs rewinding.
Heyboer does some of that. For a complete job of removing the old wire and rewiring its about twice the cost of just buyiing a new one.
There are no new ones AFAIK, unless David Hafler has one in his basement.
You can still buy new output transformers, just not specific to that amp unless Hafler does have one in his basement.
Hammond and Edcore are a couple places to get transformers but these are basically general replacements and kit & hobbyists transformers.
This looks like a very specific item for a specific application, not a catalog listing.
It is designed and manufactured for this application, and just the -C Red Medallion version, not an off-the-shelf. This is why I'm looking just for a re-wind specialist.
Unless someone can get in touch with David for me, ... I'm looking for an audio transformer specialist please.
I am using TRS and Heyboer. Both are top notch rewinding company.
Gary at TRS just rewinds transformer, Heyboer does that and makes new one also.
I've been always satisfied by both.
Heyboer is a reliable shop to get a rewind done. And he works on difficult audio transformers, and the rare and beloved.
I meant a new off the shelf similar type of output transformer from them.
Hey fellas', David Hafler passed away a few years ago. Try Heyboer.
Hey folks, how does one get in touch with Heyboer? Their website doesn't show any contact information, as I recall. I was investigating getting an OPT rewound for a Bell amp and tried email, but no one every got back in touch with me.
