Default Re: Ferrograph 4A: Restoration advice needed

Thanks both. It does look just like a bigger version of some modern polystyrene capacitors I have!

I fear the Dubilier Metal Mini-Cap it is paralleled with will not be as reliable. I have just finished replacing all the 'Visconol-X' types I can find. At least one measured as a short so I've not taken chances, as I have no other way of testing capacitors. This 'Metal Mini-Cap' is the same colour and design, but doesn't say 'Visconol-X'. Does that mean it is not the same construction, and perhaps a more reliable type?

What are your thoughts on my other bullet points?
