For grins and giggles hook up a decent 12 volt supply - even a 12 v gel cell for a while and check for drift.

I didn't pull the foam out, as I didn't want to destroy everything. After I re-assembled everything. I hung my DVM on the 12 volt line that feeds both the oven and the oscillator. I watched it vary by almost a volt. I am now beginning to suspect that I should go into the main power supply and replace at least the cheaper electrolytic capacitors. There are a couple screw terminal units that are quite expensive so I am hoping to avoid having to buy them. I will also check for out of tolerance resistors. I found several on the other board of the power supply and I suspect it is a question of heat since all the other resistors I have checked at random elsewhere in the 5110 are fine.
