Here's one on ebay and no its not mine
Item is a strong testing 19AP4B CRT. I did not rejuvenate this CRT. Was tested using a B&K 466, and also in a "sick" Zenith chassis. The anode only measured 9K volts, yet still displayed a bright raster, see picture. I was saving this as a spare for another set, but decided to make room. See my other auctions. Don't let this one pass you by, as good 19AP4 CRT's are getting quite hard to come by.
As with vintage electronics, sold as-is, no returns.
