[time-nuts] "Vanguard Ultra precision Golden Oscillator"

Hi

I think the lead length on the parts argues against them being pulls from boards. It does
*not* eliminate the possibility. I’ve seen low cost manufacture that never did any lead trim. 
I would not put it at the top of my list for “fancy oscillator of the year”. The price is high enough
that you could put together a fairly nice un-compensated XO from parts for much less money.
If it *is* an XO, you are paying a lot for it. 

Bob
