[QUOTE="Mars, post: 1120731, member: 817"] Thanks for your input handsome. I see RS has got some Vishay 500V caps at a cost. When looking at series caps, one could even use 350V caps, which are cheaper than 450V types. I have some 1000uF 200V Nippon Chemi Con caps which might work with three in series. I also have 600uF 500V photoflash which could work in series. This is a Class A amplifier with rather high DC resistance in the secondary coil of the power transformer. At switch on the voltage does not rise above 450V. I aim to use a 1K on the G1 of the 807's. I guess the same for the G2's. [/QUOTE]
