Hope the meeting goes well. Being retired here, I got roped into several volunteer organizations and spend more time in meetings than I did when I was working! I'll send pictures of the 8600A. Jeremy

Re: 141T reference replacement..a cure??
While it's true that incident light may not be a viable solution, aren't we having fun? Somebody blowing fuses, please try it! I am exasperated that I don't have time or space to examine my other 141T

Re: 141T reference replacement..a cure??
Yes, but what it doesn't address is why the strike voltage has increased. It typically increases because the pressure inside of the bulb/tube has decreased due to gas atoms/molecules being captured on

Re: On buying gear. A happy story.
Jeremy, Hi, and thanks for the email. As I said, there was an 8600 for sale recently at a very low price (fifty dollars!!) and I missed seeing it. One other is offered at some $500. Ugh. Anyway, if

Re: 141T reference replacement..a cure??
Hello David, that is a very interesting experiment you did! The LEDs that use a white phosphor have a fair amount of UVA I believe. It is possible the hanging a LED in the vicinity of the Neon may be

Re: Experience with AliExpress for connectors
I think all such sellers need some due diligence. Start a conversation with them on alibaba/aliexpress messaging, and if they are answering helpfully switch to email, research their independent site,
