Hi, all just wondering if anyone knows of a transformer rewinder out there??
There is one in the Directory, just wondering if there are any others??
I have a transformer out of a 70w amp that is 600-0-600 and 6.3 driving 4 x KT66's
I can get a toroidal transformer that will do the job for just under $200 from the US but
would like to rescue the original if possible.

Thanks all
Josh

Thanks, But by some miracle the transformer works, just needs the outer cover replaced and rubbed back.

Thanks and Regards Joshua

Pay careful attention to the wiring if it is covered by a "bell". I have had one incident mainly due to deterioration, but not exclusively, where there was arcing to the bell. After rewiring & sleeving the tabs, with shrink tube, I lined that part of the bell with insulation card (synthetic) to ensure that there was not a repeat performance.

There are a few dodgy designs around: I have a Philips 132L and its transformer is one of several of theirs where I have seen winding exiting the sides and there are some other makes with metal tabs wound into the wrap.

The later is not particularly sensible in my book as any movement, which happens, will break wires. I was lucky with the last one of these that did that as the winding was on the outside. I was tempted to take it into the local motor re-winder & coat it. I ended up putting a terminal strip on it and putting its wires onto that so that they would not move in the body of the transformer windings.
