Just found this so I aint dreaming. The 9-90-02 was in
later CC II uprights & had an IC & hoz hold IIRC. If there are
no changes other than "matching" the pins it will
be easy to make one. Really need to find someone that
has one to be sure............

My 19JC55Z has a 9-90-01B and it doesn't suffer from the waving.

I have a spare, used, 9-57 and don't mind modifying it. So if anyone has any suggestions for changes, let me know.

Also, I'll check out the 330ohm resistor you mentioned.

...I'll dig through my limited amount of Zenith Tech Tips and see what is available. Zenith and GE both produced modules that were mod'd to accept the wide range of horizontal sync from VCRs. In the early days of the web, there were even websites with suggested mods for tube and solid state sets.

If anyone else has Zenith Tech Tips, do TCA a favor and check. It'll be a day or so before I can sit down and go through them - I start in 1972 and stop in mid-1977, so it may be for nothing. Doug/DRH4683, are you following this saga???? I know Doug has some Tech Tips, and may have beyond what I have. I think the Zenith manual for the Avanti is either CM-122 or CM-123, so folks that might have the tech manual, give it a check for any VCR mods.
I don't have that range of manuals - I stop after the 20Y1C38 or similar set until the System 3 stuff. All my CCII stuff went to a friend with 6 of the EC/GC sets.

CHeers,

My Panasonic PV-4022 VCR (bought new in 1989) works perfectly with both my CRT TVs and my flat screen. No problems with picture bending.

One thing I thought of while reading the posts in this thread is the tracking adjustment on the VCR. If the tracking is off, the picture will bend. Newer VCRs have automatic digital tracking (with manual control if the digital tracking doesn't cure the bending), but older machines have a knob or a thumbwheel on the front panel labeled "tracking" that will allow the user to compensate for differences in tapes or VCRs; this is useful if you are watching a tape on your VCR that was originally recorded on another machine.

BTW: Since getting a DVD player I do not use my VCR much anymore either; I only use it occasionally to watch tapes of old TV shows and movies. (I don't record off-the-air anymore either; in fact, there is no antenna or cable connected to the VCR at this time.) My Panasonic VCR has never given me five minutes worth of trouble in the ten-plus years I've owned it, and before I got my first DVD player in 2005 I used the VCR quite a bit. But the DVD era changed all that, so when I got my first DVD player (a CyberHome CH-DVD300) the VCR quickly took a back seat to it, and is hardly used at all these days except for the purpose I mentioned earlier.
