Finally, the CTC-7 is alive!

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.
