Sorry I'm late guys. But, here is the infor.
First, it's in Sam's 84-4.
The set there is the table model version. I also have that one, and, it's the exact same chassis.
That model is 2001.
Mine is the console version.
Both 10".

It does not use a damper tube. I t technically has a damper.. It's a damper capacitor. It's connected to it's own winding on the flyback.
Other end of both go to chassis.
Value of cap... .004

The 6SN7 in the cage is Horizontal phase inverter-horizontal phase detecctor.
6BQ6 is Horizontal oscilator, and, horizontal output.
last tube is 1B3 hv rect.
Other 6SN7 is vertical osc.-vert. amp.
Uses a 5V4 lv rectifier for B+.
Set appears to have no boost supply, but, has high B+ of 410 volts on rectifier.
One of my pictures shows the .004 damper cap going from a terminal strip to chassis.
This set has a floating horizontal oscilatr that depends solely on the detector, and, sync to determine the frequency.
No coils at all.
Not sure, but, I think it may have keyed agc, but, has no dc restorer.
It is a very cheaply made set that I think Muntz could have taken lessons from. Muntz had a damper tube. Not this set. Muntz had a seperate horizontal osc. Not this set.
Muntz should have studied Bendix. Not RCa.

Entire audio circuit is 250 volts above chassis, which is B-.
They put a 100 ohm 10Watt resistor between the center tap winding of power transformer, and, Chassis.
Audio is direct coupled from the plate of the 6T8 to the control grid of 6AQ5 aud. out.
Notce a lack of caps in this set. They used as few as they could get by with.

Please see schematic. Can anyone post a sam's on this for me? I have no way of doing it.
Thanks.
Bill Cahill
