Re: HV Power Supply - 7704A - Neon Bulbs

Hi Mark,

I was just about to post that the older manual shows a 5AB-T for those. I plan to replace all four in that board (along with the caps). I have a box of A9A leaded bulbs but, unfortunately, those are the wrong striking voltage for this application. So close...

Thanks,
Barry - N4BUQ

Barry,

A 5AB is a direct replacement for a NE23. Mouser has these in stock. Get several
to have spares on hand. Broken leads at the base of neons is common.
