Hello. My trusty old Aeroflash anticollision strobe flash tube assembly P/N 073-0141 burned out and I was saddened to learn that Aeroflash is no longer in business. Whelen seems to offer a replacement for Aeroflash's $30 flash tube assembly for $230 but at that price I was thinking about seeing if I could track down just the flash tube part number and replace it (just the flash tube) for far less money. Buy chance has anyone tried do this and if so would you be able to share the flash tube part number with me. Thank you.
