SMA connectors surplus cheap
I've got a bunch of Molex 73251-1160 SMA pcb solder mount connectors extra if anyone wants some --
They are similar to current model
$5 for 5 + $3 postage for up to 25 of them. Will be packed in foam to mail without those envelopes they are pictured in.

Was only suggesting that we revert if possible to "Standard" which we had in Yahoo in this regard...but it is YOUR group and it is good to be king.
Meanwhile I will wear the letters of my delete key ...DELETE...DELETE.....DELETE

Re: Quoting Prior Messages (Re: [HP-Agilent-Keysight-equipment] Transistors for the A17 voltage regulator 8642B)
I had threading and filtering into folders in ancient Eudora and pine over a decade ago¡ I don¡¯t understand how one can manage without it, and how obsolete of an email client it would take not to have that functionality (perhaps off by default, but still easily enable-able). Every modern email reader, whether stand-alone or web-based, threads and filters messages into folders. I really wonder what sort of an antique client it takes not to have that functionality. I don¡¯t see the need to delete any messages either, it seems like useless busywork and a waste of time, since we won¡¯t ever run out of space. The time spent deleting the messages or manually organizing them is more expensive than the storage thus ¡°saved¡±. They compress well, too.
Cheers, Kuba

Re: HP 8341B Band 3 Un Levelled
I've had a problem similar to yours a few years ago with a 8340B. Swapping modules didn't help. It turned out that some of the feed-through caps (from the modules through the main PCB) had become leaky! Resistances of a few kOhms! Cleaning them (just the "isolation" part, while mounted in te PCB) solved the problem.

Re: HP 8341B Band 3 Un Levelled
Look at the YTO alignment - put a detector on it and look at slope of RG
output (unleveled). If line is relatively smooth, alignment may work, if
you see "squiggles" possible YTO problem (still try alignment)

Re: HP 8341B Band 3 Un Levelled
I didn't have this specific one but I did have a similar issue with 8340B going unleveled in Band 2 - The solution to stop the unleveling (but not to get the output back into spec) was to reload the values from the print out in the case.?
Not sure if they got corrupted, someone played with them or something else but doing that fixed the unleveled issue and allowed me to get on with tweaking the unit.
Might be worth a try.

Re: Transistors for the A17 voltage regulator 8642B
I had several fuses on A18 blown as a result of the misaligned connector to A17, I replaced them all. One of them was hard to get which was a 1/4 ampere fuse. I am currently reassembling A17 as the various SCR's and transistors appear. I will see if in fact power is getting to A17 from A18.
