On both of my 5370As, the only way to permanently fix socket problems of that type was to replace all the sockets with gold plated, machined pin sockets. On the 5370, that was easy because the boards have relatively large holes compared to the socket pins, and there is no ground plane, so it was e

Thanks, all. In this case, it was a 74ALS1035 OC hex buffer that gave up the ghost. I've temporarily replaced it with 6 diodes, which works like a charm. After all, what's an OC buffer but a diode plus a little 1x gain? Bill Ezell -- They said 'Windows or better' so I used Linux. Jürg

I don't have any of the 10811-60158s, but I did buy two of the 10811-60168s that were up for auction recently. The -60168s seem to be really good performers (from memory, -106 dBc/Hz at 1 Hz, -139 at 10, -155 at 100, -164 at 1000, when I measured them against each other.) I have never seen any sp

I'm measuring my pair of eBay -60158s right now and will post some results probably after the weekend. I've never seen the -60268s. One thing to note -- good phase noise and good ADEV don't necessarily go together. Case in point is the -60158s are spec'd at 1x10e-12 at 1 second, which is better
