GE Portacolor II needs help

[dishdude]

I had a boss that just made numbers up. I'd listen to him tell people a certain TV had 799 lines of resolution...I could hear him saying a TV was 68% solid state!

The 19" looks like an C-1 IIRC. Its 99% tubes. The SS porta color
was JA or QA chassis. One was also used in a 19". Both were short lived.
They also had a 16" that used its own chassis. It was a real dog. Tubes.
Never saw one that ran right.
Next steps were modular chassi for 13" & up. Latter a one board chassis
AA, AB, & AC. Used in 10, 13, & 17" sets.

GE was improving slowly. One more total POS 19" chassis the EC. Then
the rest were good as any. And just like Admiral when they got it down right
they soon stopped production.

I bet that's exactly what they did!

Mine is a JA. I've put a good 40 hours on it and it's still going so I'm calling this one good. I think it's a keeper.

I have a Zenith from the same estate sale that I haven't done anything with yet. It looks like it needs power supply caps, so I ordered those when I ordered the ones for the GE. I'm going to start on it next and make a new thread. Thanks to Tom C. for the schematic.

Wow that Zenith has a real strong jug. It will come out real nice.
On that set look at the main choke in the power supply. See if it has a
non polarized electrolytic in series with a resistor. This is in parallel
with the choke. Per Zenith factory its not needed & you can just
snip the cap out.
2nd thing especially on tin can Zenith sets. The ends of the terminal strips go to ground. Sometimes ones in the middle do also. They can break loose &
causes intermintants especially toward the front under the CRT. Even a
hand wired set can get a cold joint !
Let us know how she comes out.

Good to see that Zenith working.
