Default UK transformer for Heathkit IM–22 Wanted!

Hi!

Can anyone help me with a standard UK primary drop–through mains transformer to convert an American Heathkit IM–22 please?

Primary:– 0–200–220–240V 50 c/s
H.T. :–230–0–230V to 250–0–250V 60mA
L.T. :– 6.3V 3A

No separate rectifier heater winding is needed as the rectifier is an EZ90/6X4 rated for the full rectified o/p heater–to–cathode!

One with the top finishing plate would be nice but I can ways reuse the old one!

Perfectly standard "four–plus–one" size and type, nothing special!

Costs & postage met!

Chris Williams

I may end up in the stocks for saying this, but this is the sort of transformer spec. that graces 1,001 unexceptional '50s AM-only woodies with a thermionic rectifier. It's not unusual for these to go unsold at the various events, or searching "small ads" might throw something up.

Ducks hurriedly....

Hi!

I'll open it up and post a diagram of the chassis cut–out this weekend – height not important as there's tons of room vertically in Heathkit cabinets!
