Default Re: My newly found Marconi 707

Hi Ed,
That is a great find. You would be unlikely to find an untouched chassis in better condition than that.

Reforming pre-war electrolytics, don't bother I'm sure it won't work and it would probably cause damage anyway.

Looking at your chassis, it looks like it escaped the usual EMI post war overhaul. It still has the bolt on low voltage electrolytics, it also has the original multi capacitor box on the top of the chassis. There is a chance then that the tube may not have had much use.

No, the tubes can't be rebuilt any more as there is no one left to do it. I did indeed fit a Russian tube in my HMV905 as I obtained it with no tube at all.

You were clearly very fortunate to obtain it before today's news. I don't think that picking a vintage TV set constitutes an essential journey, though I have often tried to convince the wife that collecting TVs is an essential part of life!

I wish you will with the testing.

BTW, the tuning has a ball reduction drive, it can get clogged up with dirt.

Cheers
Andy
