[Amps] Alpha 374A broken HV capacitor

[Henk PA5KT]

Hi,

I had suddenly a lower HV voltage. It appears that 1 of the 6 HV 
capacitors is broken.
I am planning to replace all six.

I found some companies who deliver replacements.
Looks like Harbach has a good deal for 8 of them, guess they will sell 
me 6 as well. Dont know if they deliver to EU.

As I have to disassemble the board, what else should I replace?
