Dear OM

A friend of mine has a broken Kenwood TL-922 amp. The faulty part is the
transformer of the power supply ("T2", according to service manual), we can
tell and smell from the smoke coming out of it.
The Belgian Kenwood service center does not have this part available
anymore, and according to them, both the stocks for this spare part in the
USA as well as Japan are exhausted.
Now, my question is: does anyone know where to find this part, and if there
is a manufacturer of equivalent transformers to replace it?

All help would be greatly appreciated!

Ouch. (my AL-80A suffered a similar problem though luckily without smoke!)

Has he tried Peter Dahl http://www.pwdahl.com ? They've got a pretty wide
variety of transformers for amateur amplifiers. (I do wonder if it's less
expensive to buy a new amplifier than to pay the shipping charges to have a
plate transformer shipped from Texas to Belgium?!<grin>)

Failed transformers. In the "old days" we used to re-wind them. I've done
a few myself.

You loosen up the windings and insulation by burning it out with a blow
torch, then measure the wire size, un-wind it, re-insulate and re-wind it.

Remember to count the turns and make a drawing of the winding layups as you
unwind it...

It's fun... and you can often make it better than new.
