I have not tried it but, I was wondering if a capacitance multiplier circuit could be used in place of the enormous H8 power supply capacitor? Here’s a link to the concept:

I would say it's a bad idea. The issue would be the current, these old machines use a lot of power via linear power supplies. This power is best tamed with brute force. Finding a semiconductor to handle the current would be hard.

It seems the ones for sale on Amazon are almost all the generic Chinese ‘big reds’, which fall into two versions, the 1000VA model with analog meter and one outlet, and the 2000VA model with a digital meter and two outlets. eBay seems to sell mostly the same two, plus lots of vintage ones that are all over the place in their specifications, and not any less expensive than the new ones. You have to be careful with the specifications in the listings, often the sellers don’t know the difference between voltage and power, or write laughably silly things about them.
