Hi!

If Ed's unable to do it or he's a bit expensive for you, one of these might do the job for you if you connect the secondary windings in series to give a 2:1 ratio:-

I don't have a VCM163 as the stratospheric prices being asked for these have put 'em beyond my reach even if I saved up for ten years!

You might be able to cut a sheet of SRBP or blank FR4 PCB material with two mounting holes drilled to fix it to your VCM163 chassis with nuts, bolts and spacers, then drill 6 x 1mm holes in it for the transformer to drop into, with the wiring from your VCM163 soldered to the transformer pins on the bottom side of the mounting plate!

PS!

I presume you're referring to the Oscillator Transformer T1 on the Power Unit/Oscillator Panel and NOT the dust-core tuned T1 on the Amplifier Panel?

PPS!

I've just looked at the Component Layout Drawing and it's only a simple ferrite pot-core job - before you get hold of Ed, it might be worth taking it apart to see if you can get at the primary ends - it might only be a spot of corrosion at the pin-ends you might be able to repair!
