Finally, the CTC-7 is alive!

Your color bars almost look like a purity problem the way the color varies slightly in different areas of the screen - though it could just be the way the camera captures the screen.

Looks like your on your way to getting this set rehabilitated.

Well, this makes me very happy-- especially since when I found it, it was a rescue set that might well have been discarded by its previous owner.

Just wish I had techs around here that were up to the challenge of bringing one of these old girls back to life... but I'm glad she found a good (well, actually a **great**) home!

No you're right, it's still a purity issue I haven't gotten to just yet.

And actually, I have horizontal drive issues to work through still. Cathode current is still hovering around 212ma, where the manual says to keep it under 210. I'm gonna shoot for 160-ish just like I did on the CTC-9: so far I've adjusted the sine wave coil for 'equal peaks' as per Sams using the o-scope, next I need to check the drive waveform at the 6DQ5 grid to make sure it's at the correct amplitude. My guess is there are drifted resistors in the horizontal (drive) circuit, because even with the drive control at it's max, current is still high. Just in case though, Mark let me borrow his fly ringer to check for winding issues. I should have an update later today, after I get off work.
