Thus spake :
Hello!
I look for a pair of 220V power transformer for TL50+. Please let me
know if you have ones for sale.

Thanks!

If you are desperate & cost is not an issue AND you have a faulty one, there
are a few companies that will rewind transformers. The task involves gauging
the wire thickness then counting or estimating the number of turns & taps.
The same companies may even make up custom transformers to your
specifications.

The closest I got to using such a service was at work on a piece of HP test
gear where the cooling fan was shorting across a 110V primary before I
realised the fan just merely needed replacing.

Maplin may have a limited selection of new mains transformers as do trade
suppliers such as RS & Farnell. There must be thousands of scrap
transformers either removed or still in equipment across the planet but like
many things, what's worth gold to one is worthless to most. eBay must have
paired much priceless "junk" with new owners! just think what we could do
with telepathy. I wonder if there is a missing glove matching site? Good
luck anyway.
