[time-nuts] OXCO Issues

I looked inside the OCXO and didn't see anything obvious.  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.
