@8bitforlife got some recently. Don't remember who from though.They started smoking on a chassis that my buddy has. So they need replacing. Anyone know a part number or where to get them?
First time for everything. Indeed, they were smoking on the MS2930. Probably took the tube with it.never seen a spark gap smoke, being fixing chassis since 86
If you have a manufacturer or part number that could help.Not sure I should say so they dont get bombarded.
I believe there called spark caps and I was only sent 2 or 3 to fix my chassis that's been to a certain place 3 times.
I eventually found out with inspection that one leg was not connected and it shorted my tube.
There is a PSA posted about these chassis. I know that my tube is shot as well as another members here and we both had issues with the vacuum tubes/spark gaps/GDT's. From my experience, I definitely saw it smoking.they are usually called GDT's (gas discharge tube),
how can it smoke unless the glass breaks???
you may want to check the soldering incase that's what's smoking.
also they come in voltage ratings - you need to know which one to buy.
Did a bit of Googling on the matter and came up with some info on the probably causes:There is a PSA posted about these chassis.

I'll pull mine from the neck and see if I can get something off the print.
I am going to give that a shot.@acblunden2 your tube might be just shorted. You can try a rejuvenator they have a short fix feature on them. Its worth a shot.
Found a data sheet info on that closely matches that part number, so it looks like we are getting somewhere with thisi am not fixing stuff from far away due to the costs but happy to try to help id the actual problem
there is not a lot on those ms9 neck cards, there are safety resistors on each colour
the spark gap part number is RA-102M-V6-Y-2, you could probably find an alternative using part or all of that number
HV shutdown on ms9 is pretty rare, they shutdown on power up if there are any issues in vertical or horizontal or sync processor circuits
