Good Morning:

Before I run off to work today, there are a number of things I would like to
see you test if you want to & have the time......
Both at the IF section, and again at the HV section.

At the IF Section, I know this may sound silly at this point, but, I think you
should check the input RCA jack the center connector where the signal goes
in, I think you should check this to ground with the ohm meter, to be sure
it's not grounded.... Please post the actual reading as well.
I think you should disconnect R23 at pin 3 of L3, and Disconnect Pin 1 of L3
and then put in your DC AGC bias circuit for Point A. Fire it up and see if you
can feed a signal through..... Be sure to sweep the voltage on your little AGC
bias circuit. If no signal, then I think you should reconnect everything,
disconnect pins 2, & 3 of L4. Take your tuner subber and ground pin 2 of L4,
and using your coupling cap attache the tuner subber to pin 3 and see if a
signal makes it to the screen..... Without a plate voltage there I'm not sure if
it matters to leave V1 in for this part, or take it out.

Not sure how I feel about disconnecting pins on K1 because it can be
overridden by the AGC Bias thingie. But If you really want to remove
a Pin & Test, I would remove only pin 5. Be sure you use new batteries
in all of these things for testing.

Other thing I would like to see is a resistance or Ohm reading from these
points to compare against the Sams for the following areas.....

Tube | Pin | Sams Reading | My Reading |
--------------------------------------------------------------------------------
6JM6 | Plate Cap Both | 22 Ohms | ? |
3AT2 | Plate Cap | 622 Ohms | ? |
1V2 | Pin 9 | 21 Ohms | ? |
6BK4 | Pin 5 | 800K Ohms | ? |
6DW4 | Pin 2, 7 | 24 Ohms | ? |
6DW4 | Pin 9 | 240K Ohms | ? |

-------------------------------------------------------------------------------

Please double check the resistance table & be sure I did not make a mistake
here. Also observe the little caveats posted in the Sams about each reading.
I'm interested in these as a double-check for flyback wiring, just -in-case.

Don't forget to stop for coffee breaks now & Then and have
a good lunch & think about next steps.
Never Give Up, Never Surrender.....

Have an Awesome Day!
