Yeas ago a friend of mine worked at Executone in Long Island City.
They had pile of these with matching single low band FM units, both used
tubes.
The mobile version of those amps put out around 40 watts with good 12 volt
heavy wiring (2 sweep tubes with 450 volt inverter)

I seen a Sonar brand RF Linear - Model BR-21 - last evening. It had no
"Band Select" switch on it - so am wondering, what purpose it served? This
one was in ok condition - but not sure if it worked.
