Those are DC link Capacitors. I have used them for years now in
amplifiers. Not that brand though.? I used the 944U. They make
them up to 1.4KV at 70UF.? Or 1.2KV at 100 UF.? That is full
working voltage and you are allowed 50% more at less current. They
are rated in AMPs. So in HV B plus service you would never pull
any serious current. They look like a hockey puck and are easy to
mount. I will look into this new brand.?
