I think most TT rigs are air deprived. The Omni 6's I had needed some air
inside badly. When receiving, it was stable but after sending for a few
hours at high speed, the oscillators would drift due to heat conducted
from the finals. There were 2 cures. One was to keep a fan blowing across
the heat sink on the outside and my final cure was to remove the speaker
and install a small fan in the bracket. It fit perfectly and blew air out
the speaker grill. I used a 24v fan from an HP printer. It was virtually
silent and stopped the drift. When I sold the rig, I simply removed the
fan and put the speaker back in it. The corsair and Omni A-D series were
sealed up with no velilation too. The same thing happens with them after
transmitting for a while and I'm going to do something along the same
lines. A cheap solution is to leave the lid off but maybe one could get
the lid perferated somehow. About 200 holes would do the trick.
