Probably a stupid question but should I be concerned if when setting the bias on the 2230 if the reading for mV won't remain stable? Input selector is on Aux and volume is turned all the way down. I have the leads connected to J757 and J758 and adjusting R765 for 5mV and in the past when doing this on another unit the reading would stop fluctuating after the unit has stabilized for 30 mins or so. It's close enough to 5mV put it does jump from 4.8 to 5.4 back and forth continuously,so I would think it's a minor concern but what would cause it to fluctuate like this? Most of the recap is complete with the exception of the 700PCB and the large caps. PS voltage set no problem at 35.6V as per the SM.
