I haven't seen this discussed in the archives . . . Several years ago (actually MANY years ago) I ran a Heathkit SB-102. I never turned it off. Generally I put a muffin fan over the finals and pulled air out for cooling. Sometimes I simply opened the lid and let it run with convection cooling. I wanted the LMO to stabilize and to avoid turn-on shock to the components. I never had any problems.
Now, a few years later (ok, MANY years later), I've put together a B line. I generally turn the T4XB on a few minutes before transmitting, and use a muffin fan over the finals to exhaust air. The R4B I run continuously, with a fan as an exhaust over the LMO. The R4 LMO is used for frequency control. Everything seems to run cool and is stable. Although the LMO's are reasonably stable after a few minutes from a cold start, leaving the receiver on does seem to make a difference. The transmitter runs much hotter and I hesitate to leave it on all the time. (Saves power, too.) Am I setting myself up for a problem? Thanks!
