Hello! I'm new to this site and am looking for some help. A customer and friend of mine recently gave me a MX-9644 tube and I need a housing for it! He told me it would fit a AN PVS 4 and that I should easily be able to find one on eBay for 200-300$ for the housing only. I can't seem to find a housing anywhere online tho! My question is, am I looking for the correct housing? Will this tube fit any other housing? (Have seen alot about TVS-5?) And does anyone know where I can get a housing to fit this tube? Going on a pig hunt next month and would love to get this thing operational by then! Thank you in advance!
