Can anyone tell me where I can get a viable alternative for C32 which is 32μF 300v elecro capacitor.

Thanks

Use the next capacitance up 47μF, and use a 600 volt.
Even though the negative of the cap is connected to the centre tap of the power transformer, I would not use a 300V.
Plenty available, WES in Sydney, Carl on Ebay.

A trap with modern electrolytics is that most do not tell you the peak, or surge voltage like the old ones did. If you have a rectifier like #80 /5Y3, or anything that behaves like one. There is a delay between heater warm up and conduction. That creates as urge voltage that can theoretically be twice the running volts.

I will not use anything under 500V, but prefer 600V where there is a filament rectifier like 5Y3. and a running HT of 250V.

You can use 300V 60μF caps in series with a 220kohm resistor in parallel with each cap to maintain equal voltage across each cap. Might be economical if you have them on hand.
