So far I have;

Good grounds everywhere on the camera side. Foil to foil, foil to both RCA connectors, RCA to RCA.

39K ohms on the PE internal measurement within rld notes and specs.

Tested the PE output with a flashlight. On a 200maDC scale I got levels between .1 and .4.
It sees light as I move the flashlight around but not sure if that is a correct level.

Using the same 200ma I measured the main out audio. I got -0 to -104 or so. Minus?

Using my 1992 RS mini amp/speaker I listened to the output.
I got loud modulation hash with it changing pitch via the flashlight.

I cleaned the 24 ports on the disc. All good.

The camera seems to be trying to make a picture. Time to move on to the receiver. I will start with the NBTV disc to see if it can be stable even with the scan mismatch. 24 vs 32.
I am also thinking of changing the power cords to a grounded version. It cannot hurt. Peter's amps are well sealed and a problem to open. Still working on the letter "A" test card.

rld...I will try to record the flashlight test version via Audacity. It will be a moving blob but will tell you if your receiver can see it. It should be a small file if you send me your email.
