Need help-Bendix tv

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.

The 2001 schematic is attached. As for adding a vertical blanking pulse to the
first grid of the CRT, I would add a 22K 1/2 watt resistor in series between the yellow wire and the capacitor because I don't know if these old CRTs can withstand that 60 to 80 volt vertical pulse and not develop an G-K short.

Another way would be to send the pulse from the yellow wire through the resistor and the cap to the second grid. You might need to add a second 22K resistor in series with the B+ source that is connected directly to this grid.

Best luck with this set!

I see G1 of the CRT connected to the cathode of V7, not to any B+ source.

The previous sentence mentions "second grid".

P.S. I mailed the schematic to Bill last Friday.

Thanks. I'lll be watching for it in the mail. I still have to finnish the table model version of this set, as well.

I think the movie you're talking about is Avalon by Barry Levinson, who also made Diner. In fact, in one scene in Avalon, the kid looks out the back window of the car to see them installing the diner from Diner.

That movie has a great scene in which the family sits enthralled by their first TV, staring at a test pattern. The grandfather finally says that to him, it doesn't have what radio has.

Yah, but he carried that Admiral in like a bag of groceries, and, didn't even connect an antenna!

I loved the scene of all the tv's on in the store.
I was heart broken after the fire when all they found was the bront panel of a GE locomotive set.
Of course, where did all the gutts go???
Nothing left of anything??
Heck, there was even more left after a blaze on another movie I liked.
This movie is just great!
