The R-390/A is also especially useful in the winter as a space heater, and in mobile homes as a preventative of being blown away in a tornado.

I never owned a R-390, but I had a number of R-392s
(mobile version of the R-390}

along with a few t-195 transmitters.

Collins was noted for great selectivity and stability, but never too hot on sensitivity.

Yea, they are that.

My hamshack as a kid had the following: A Hammarlund HX-50A, Collins 75A1, a homebrew 813 amp, a National receiver from a USN contract (it sorta looked like a HRO-60) and various other stuff.

In the summer, I could operate only very early in the AM or late at night. It heated up the house too fast otherwise.

Still, I think the audio (both transmitted and received) on some of the old tube boat anchors is far better than the modern stuff. Especially on AM.
