[sdiy] 910 pF caps (Buchla 292C/266-3)

[Chris Crosskey]

Unless 910pF is required for the application in a tuned capacity then it's
probably a quirk you sometimes find where people have to buy a specific size
for one job and then use it all over to hold the price down.....he needed a
910 pF for somethign and ended up fittin gthem everywhere anyone else would
have designed in a 1nF becasue it wuld be close enough in a non-tuned
application...

If you need to feel sure, then check the 1000pf adn use the ones under
spec....
