Tom,

I believe your Sony monitor uses the same modules as my model 2500(minus tuner and IF modules) My set has chassis U-807. It's in Sams 979, folder 2, dated 9-68. It's a tough Sams to scan, the schematic is a 4 page fold out.

I'm sure you're dying to see the front side too.

She is a beauty!

I've found the local FedEx and Kinkos tend to have large format scanners that do a good job with color TV sam's prints....Heck I'd be happy with legible pictures of the schematic.

Could you look up the focus coil's ID number and any subs listed in the sam's?

[Kevin Kuehn]

Is your focus coil just dangling off a wire going to the horizontal module?

Here's the coil data from Sam's. I'll see what I can do about a scan in the morning(I mean much later this morning), depending on how crazy it gets around here. Maybe pm me your email.

Yes and no...It was supposed to be a front panel control (under the underscan sub section), but it is missing there....Three wires near where it is supposed to be are spliced with electrical tape to a 3 lead cable that goes to the dangling focus coil. I ought to trace those wires, but some go to the underscan switch which complicates things...

I was able to get 11KV and a lit screen (with unfocused unsynched color video) from it tonight by unplugging the HV regulator and bridging the open part of the focus coil with a 12ohm power resistor (which stoped the internal arcing in the coil). There are 3 100uF 450V lytics in it that are lousy, which I can't even make a good kludge replacement for...B+ was dropping and it smells bad (cap juice me thinks) so I'm probably going to put it on hold till I can get those caps.

Perhaps you do...If you take comedic exaggeration seriously.

I probably take it too seriously, as well. I have $135K invested in just the buildings to keep it.
There's probably others on this forum that have that much or more invested. I have met a few that have a lot more than I have invested.
Tom or Nick wouldn't have had to worry about me bidding against them. Buying a rust-bucket never appealed to me. Too disappointing! As much as I appreciate the quality of construction of S-C products, I never considered them as being stellar performers, at least, not that much better than the higher end models of Zenith or RCA.
I don't know why Nick would want it, unless he has a S-C that he's repairing.
PS, If I had a Setchell-Carlson color set, I wouldn't kick it to the curb.
