Cleaning my Marconi MK3 IO camera

[AndrewM]

Nice work on cleaning up the camera. The units are looking quite good after their clean. I notice some mods here and there and also some component replacements.

Reading through your comments at the end of the pictures, I would not recommend replacing components just because of their age. For a start, most of the capacitors I've seen are Philips polyester (mustard) types which have a reputation for high reliability. The resistors are easily enough measured as well and most should be in tolerance.

The PSU looks like it has already been recapped at some stage. The Elna can electrolytics must be very late 1960's or more likely 1970's vintage. I'd try reforming them before attempting replacement. Electrolytics can often be put back into service after years of disuse with some careful attention and will save you a LOT of money if they can be reformed.
