[BC] Gates 250T Manual needed...

[Dana Puopolo]

Did they have a 4 pin base? I had a RCA BTA 250GY (I think) when I worked for
WAMO back in 1977. 
It was the aux. to a Collins 20V1. It was remoted with a T arm connected to a
gear/motor drive that turned all the circuit breakers  (located on the bottom
front of the unit) on and off.

I replaced the Collins with  McMartin BA-1K (that's what they bought me),
after its plate transformer died. Later on I got a transformer out of a junk
rig and got the Collins going again (it became the aux. and the TCA just sat
there).

That station was a 1 kW 2 tower daytimer on 860. It had one of the best
signals for a 1 kW that I ever saw!

The first AM I worked on in 1970 had a BC-250-T. I don't think it had
833s. As I recall, the tubes had a cap on the top and one on the side. I
don't remember the type number, though. Things I remember about that is a
bunch of 807s mounted on a big circuit board on the right side of the
transmitter with the modulators and finals on a shelf above. On the bottom
were the mercury rectifiers. I was always afraid to turn that thing off
for fear that I'd have trouble with the mercury rectifiers on power up.
