[time-nuts] 5065A Rb Cavity Rx - SRD repair

[Ulf Kylenfall]

Disassembled the surplus Rx cell by first disconnecting 
the short jumper cable and then unscrewed the brass 
part. Inside was a tiny diode, color coded "391" 
as have been previously discussed in a thread some years ago. 

I recon that if a diode would some time in the future breakan external multiplier featuring modern semiconductorsshould not be that hard to design and connect directlyto the loop in the other end of the jumper cable.  

Actually, I was expecting something in a tiny ceramic 
package with a UNF thread in one end and a gold plated 
cap in the other. Not anything that looked like a 1N4148...
I could see that the bottom coax part of the SRD assembly 
had been filled with curing silicone after the diode had been put in place. 
Removing/replacing it would require using a drilland fixture but it should be doable without 
cracking the glass...
