Greetings gurus!

Any comments on the proposition of completely submersing a GS-35b (with stock cooler attached) in a cooling bath of dry transformer oil?


Basically, I have no interest in a nasty howling centrifugal blower in my shack. A quiet hum from a rubber-mounted liquid pump will be annoying enough.

Can the GS-35b operate at such a low temperature of 45-65 degrees C?

What effect will the oil submersion have on its' RF operating?

What will be the effect of close-housing the tubeset in a sealed alloy box?

RF discussion please. Mechanical and/or other problems will be addressed later AFTER it is established that it is a viable proposition RF-wise.

All constructive criticism welcome.
