Looking for some advice on the best capacitors to use in power section of this oscilloscope circuit.
Some Background
I purchased what I thought was a 1952 Cosser 1035 scope only to find it had been gutted and completely rebuilt with a customised circuit. I’m slowly drawing a schematic from scratch in able to analyse the circuit before restoration.
My question
The top transformer has 5 large PIO capacitors (Top RH of circuit marked numbers 1 to 5) one of which is leaking oil badly. I am aware of the toxic nature of these and about safe disposal. There are also 2 large cylindrical caps, also possibly PIO that failed testing so they will need to be replaced. (0.1uF 3000vdc).
Not being familiar with this rather complicated power circuit some advice on suitable replacement types for these capacitors would be apreciated.
