[R-390] R-392/T-195

[Jim Brannigan]

I had a T-195 and between the dynamotors and the fans it sounded like a
demented vacuum cleaner.

You can't operate it out of the case without defeating the safety
interlocks.  Also the fans have heating elements and sensors on them.  If
the fans stop the radio shuts down, these would also have to be defeated.
The input is filtered to keep dust out of the enclosure.

With all that said, it should be possible to operate the radio out of the
case and shut down the squirrel cage blowers.

However is very important to leave in place the fans for the final RF and
modulator tubes. They are in "air system" sockets and require a minimum air
flow at some level of back pressure. Without the air flow they will quickly
self destruct.
