Default Re: Replacing polarised capacitors (condensers) for Pye Record maker

Blimey, this is some "big boys toy" should you have the magnetic discs and associated recording head. Also, not too many domestic products have a busbar to keep earth loops at bay. That's the bare wire running the length of the chassis.

Now getting down to the nitty gritty. Other contributors have suggested component sources etc; but I wonder if I may add my two-penneth.

Your only real problems are with ANY Hunts cylindrical capacitors. Those are the brown ones and have a dreadful reputation. They are only a few. The other "change on site" right away are the Plessey electrolytics. They are the yellow ones with a red band at one end. This is the positive connection AND it is important to wire replacements correctly.

The wax coated capacitors have for some a poor reputation but looking at the schematic, I believe that they are not stressed and could be left alone unless, following the above, the record maker doesn't work.
