Yeah, that's right Tom.
Its the same with the AL-1500 model. More caps, higher voltage but they
are still right on or over the limit of 450V per cap.
I changed mine for higher value, 500V jobs. I was able to fit 16 caps in
the space where the 8 originals were. They are arranged as a string of 8 x
2 x 330uF/105°C caps in parallel. That's 8 x 660uF in series to give me
82.5uF at 4000V.
There was nothing wrong with the 8 x 220uF caps. I just got nervous
running them that high.
I bought them from the US, on the bay. They are probably cheap charlie
ones but they do the job really well.

The problem is - the Ameritron ones are rated at 450 volts. That seems
like
they are operating at pretty much their max. This one has about
1800-1900
plate voltage. Four of the Ameritrons are 1800 volts rating (unless they
have a built-in safety factor). 73
