[R-390] 51J AGC and PTO questions

[Tom M.]

Anyone ever slowed down the AGC action on your 51J?  Mine is really fast and it
has an annoying pumping action to it (don't know if it has any mods).

What cap on the AGC would be right to slow this thing down for SW broadcast
use?  390A uses 2 uF for MED.

Also, did anyone notice that the PTO endpoint error varies with line voltage on
the 51J?

I set mine spot on about 5 years ago.  It is now 4 kcs long on 120VAC and 2 kcs
long on 108 VAC (using a 12V bucking transformer box).

This PTO moves faster than kudzoo weed, but I guess one could use a variac to a
limited degree to tame the PTO endpoint until such time you could dive in
again.

Thoughts?
