I thought it did seem kind of weird while I was looking at the schematic today, so I used a 250V 10uf cap to see if I got any improvement in the evenness of the brightness, but I did not.

However, Sony used a 50V part there. That's what I pulled out of it (it was dead, but it said 4.7uf 50V), and that's what the schematic says it should be.

Try a 5 or 10 meg focus control so as to not load down the supply voltage.

I don't currently have one that big. I have 1.6kV diodes though! Would it make sense to throw a diode between the 530V and the 1M potentiometer to prevent load? Like this:
