John,
I'm working on a Vaiant* for a friend, and I ended up using eight 680pf @
1KV in series-parallel (4 parallel pairs in series). The caps I used were
the CDE "snubber" caps, available from Mouser. Between these and the
analogous 40 meter fixed caps, it the total was around $60. But, they are
working well - no flames, smoke, or bad odors :>)

So the Valiant is putting out 100 - 130 watts into my load or antenna on
all bands - I put it back in it's cabinet (mistake..) and cabled it up.
Having previously set the mod bias, I tuned 'er up, opened the Audio pot,
gave a couple of whistles and the 160/80 M capacitor stack "deviated from
spec" in a rather spectacular and stinky fashion. O well - at least I
understand completely what needs to be done - and about $60 worth of the
correct RF units will be delivered to me on Tuesday. Wouldn't have been
so much, but I bought heavier than required and also spares, just in
case....
