New Variac for Joule Electra Amps


I have a pair of Joule Electra VZN-160 amps and have been using them happily for the last six years. They use a single outboard variac for voltage regulation. I how have a problem where something inside (the core) is glowing and a burning smell starts to manifest.

I'm able to send it in to their out-of-warranty repair facility for a likely core replacement (likely $500ish or more) though it will take ten weeks before it ships back.

Has anyone got other ideas on how to fix this issue? Is there any after-market variac that would work, or could I just somehow get a new one?

Thanks in advance for any suggestions.

I wanted to post the fact that there was a happy conclusion to this issue. I sent the kaput variac to Richard Brkich at Signature Sound. Rich is pretty familiar with the Joule amps and uses a pair himself. He researched my variac, got a new one(higher spec/capacity) from a great source for a great price. He then did the custom work on ensure that it would work perfectly in my application. I got the variac back in a timely fashion and there was always excellent communication and attention to detail along the way.

Independent of Rich's help, I bought 16 new power tubes as it became clear that I had some runaway current on at least one tube.

I'm not back in business with a wonderful sounding pair of amps that are very stable and the variac is prefect again.

I could not have hoped to work with a better technician/expert than Rich - he was a joy to deal with and I cannot recommend him highly enough if you ever need any work done or if you are in the market for new equipment. His advice and recommendations were thorough and super helpful and he was very generous with his time.

I'm back to a lot of happy listening now (exploring my new Tidal subscription and exploring more vinyl with a new Thor phono-stage as well). Happy listening!!
Thanks Swampwalke.

I meant to say ..."I'm NOW back in business with a wonderful sounding pair of amps" and not 'I'm NOT back in business..." ;-)) Spelling is not my forte sometimes.
Happy to hear Rich was able to help you out. Is Joule Electra still in business? Jud hasn't been at any recent shows as far as I know.
I believe that Jud is no longer handling day-to-day activities for the business, but Simon Thatcher seems to be involved in the business and managing communications in a timely manner when I reached out to the Joule email alias.
