HELP! - Need a Repair Recommendation for my Raysonic Amp

After 5 years of flawless service, my Raysonic SP-66 tube integrated wouldn’t power up yesterday evening. The fuse at the electrical input was blown, but it still didn’t power up even after I replaced the fuse with one that tests good. I took the bottom plate off, looked around inside, and didn’t see anything obviously wrong. The 2 internal fuses tested good.

It ocurred to me that the power button was probably in the ON position when I went to start listening. This suggests that either I accidentally left it on the last time I listened, or one of my grand-children turned it on, and it over-heated. I also noticed a paint blister on one of the transformer covers suggesting that it over-heated.

My suspicion is the power transformer, but I don’t how to confirm it, or replace it if it is in fact the problem.

Raysonic is long gone and they had a reputation for being secretive with product details, so I doubt that anyone will have schematics or parts values.

The amp has been a pleasure and it is a perfect match for my CD128 CD player which has also performed flawlessly.

Therefore, I would very much like to get the amp repaired, as long as it isn’t cost-prohibitive, but I don’t know who to turn to, much less trust, to do the work.

I would hope that a well-qualified tube amp technician would be able to fix this even if they are not specifically familiar with Raysonic. I just don’t know who that is.

So, I would appreciate suggestions/recommendations of someone who may be able to help me out.

Thanks in advance.
