Dan, those are the words of a genius! What better way of disguising a still
from those pesky Excise men... This could encourage me to thow away my solid
state PAs and return to the tube fold......

Serious-ish note. Just in case you are wondering, water/alcohol mixes go
into the vapour phase at too high a temperature to make them viable for
cooling solid-state PAs. A reliable SSPA will be designed for junction
temperatures of 120C.
