Shouldn't overheat merely being left on. If it did, the transformers would be the last to get hot. Transformers don't generate hardly any heat in normal operation. They tend to last pretty much forever. But they are made of coiled wire, which if poorly insulated could short and that would create a whole lot of heat. You could test for that pretty easy with a volt/ohm meter and some basic transformer knowledge. Or like you say any reasonably good tech should be able to diagnose and fix. I would call your local audio stores and ask for a recommendation.
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.
