I am looking for a multi-ratio modulation transformer of around 250 watts audio power rating, in working condition, to buy.
Suitable types would be the Woden UM4, UTC CVM-4, UTC S-22, Stancor A-3898, Ken-O-Tap T496, Thordarson T-11M77, Thordarson T-19M17 or any other modulation transformer of similar ratings which has tapped primary and secondary.
I will either collect in person or pay for carriage. I am located at Ross-on-Wye in UK.
