Re: Russian Doorknobs?

Some Russian ceramic capacitors will actually have their KVaR rating printed on them.

?

The print will have a number like ¡°90#&.¡± The Cyrillic letters I forget, but

they do exist, as the caps will have their tolerance in %, voltage rating in KB

capacitance in another figure and amperage rating in another.

?

You know the cap will handle rf amperage when it states a current rating.

Greg,

In my 8171 amp I use two Russian 470 pF caps in parallel for plate
blocking, dont remember if its the KI5 type but I could check ofcourse.

I know that I have seen some Russian capacitor data somewhere on
the internet but cant remember where.
