Default Reviving a Rediffusion Mk1 - variable transformer to 'warm it up'?

Hi,

I recently bought a job lot of Rediffusion Mk1 TVs from a retired TV repair man which I'm in the process of trying to revive and see how many I can get to work.

The guy I bought them off suggested that as they've been in storage for a while that I should warm up the capacitors by passing ~10v through the sets first (using a variable transformer) before trying to put 240v though them.

Does this sound like a sensible approach? I'm having some difficulty getting my hands on a variable transformer to do the job (they are pretty expensive for something I'm likely never to use again), are there any 10v (or 12v etc?) power supplies that would do a similar job that anyone could recommend?

I've been scouring the internet looking for assistance getting these working, any help would be much appreciated!

Thanks,

Adam
