I had come across the use of paralleled XC18s and experimented a bit - I discussed it with Grahame Marsh some years back when he was doing his trigger clock - I'd still like some *real* XC24s though - paired XC18s don't behave terribly reliably (current obviously doubles when second tube fires)...
There are a lot of XC18, XC24 & Z700U etc. circuits in the standard texts (Dance, Bylander etc.).
