[Central-Electronics] MM-2 advice

[K6JEK]

I brought a dead MM-2 almost back to life but now I'm a stumped.    
The high voltages are low and I can't position the trace down to  
center or below.   Anyone have this experience?   Any advice?

I followed Nick Tusa's advice  ( http://www.tusaconsulting.com/ 
mm2_service_notes.html ) except I haven't replaced any of the pots.    
I did replace all the electroytics, the famous C17, the HV voltage  
divider resistors, R73, R4, R5, the sweep and audio oscillator micas,  
all of the paper caps while I was at it and the line cord and AC  
bypass caps.   I was pleased that it came to life after this having  
been DOA.   But as I mentioned the trace is high, I have to adjust  
the pot all the way to D (own) to get it close to the center and high  
voltages read low.

Out of the power supply, the voltage is fine, 1080 V at pin 2 of the  
5Y3, just as the manual says.  But  at A it's 927, not 1000V  and  at  
B 824V not 960, suggesting something is drawing some unexpected  
current.   Gosh.  I checked the oil filled electrolytics by subbing  
(then un-subbing) modern electrolytics.   I even checked the ceramic  
caps C13 and C13A by disconnecting.   I know I'm running out of ideas  
when I'm checking ceramic caps for leakage.   I also checked the 2.2M  
resistors feeding the top and left deflection plates.

Any suggestions would be most appreciated.
