Valves for my Marconi 702 mirror lid.
I have nearly finished my 702 restore (write-up to follow). However, I am in desperate need of a 5 pin MSP4 as the one in the frame sync separator is nearly dead and won't hold vertical lock. I would really like a couple but let's not be too greedy!
Naturally, all costs paid plus a reasonable charge for the valve itself. I have tried the usual outlets such as Langrex etc. but they seem only to concentrate on the audiophool market.
