I determined today that the chassis puts out 7-8 kv for the convergence grid with an ultor voltage of 16 kv. Nick can now try these voltages and see if he can get it to converge.
I also have the regulator circuit working in the range of 14-16 kv. With everything considered, I'm fairly sure that the chassis was designed for an ultor voltage of 16 kv.
Today I found a connection cut and a bad resistor in the negative power supply divider network. After fixing that and doing the alignment again, I now have working AGC and sync, plus proper gain for the IF strip.
Tomorrow I'll work on the reference oscillator.
