I have a module box on my 61 modular 10ee that is misbehaving. I know because my backup box is working great and I can't get over 450 rpm with my original box.
I noticed over the last week that the drive was hesitating a bit. I was thinking that since I replaced all of the diodes recently that I might need to set my compensation & speed pots again.
I suspected a problem with the new diodes because I made replacements using a soldering iron, & I am lousy with a soldering iron. I replaced all of the new ones with the original diodes and still have the same condition.
I have tested all of the resistors and no problem there. The capacitors all measure .90 to .98 microfarads on the capacitance test, I suppose that proves they are functional.
The potentiometers all show the same resistance as when they were new between the various poles.
The connectors are good and all stand straight up (to the tube board).
There are a few components I don't know what they are, they look like small resistors and are marked Good-All 663UW .001 5%. What are they?
Also are those box shaped things the suppressors? Mine are blue grey marked GE 5L 6RS21SA13DI3. Any suggestions on how these could be tested?
They are black in this picture marked 3D13 NG

I don't think I am going to send this one to Monarch for repairs because I can buy the scissio.com replacement cheaper than Monarch would fix it.
Thanks for any help
