Please note that they are not all mine, but bringing them back to life 
together sure helps.

C8, C9 and C10 does not feel happy in either of the three units. Loosing 
legs is among the common hobbies for these caps.

C11 is also replaced as it was also running warm.

C5 is my main suspect for being bad, but it was not my main focus this 
evening.

It's really cheap to replace these caps, doing it in advance makes it 
much cheaper and easier.

I also realized that my trimming experience with these will ripple over 
to the trimming of other large rubidiums in my lab. One of the trimmings 
I've learned to do on the HP5065A will surely help to improve the 
performance of the other rubidiums.

Cheers,
Magnus
