Thank you Eric, the summary sheet is very helpful! While I prefer round shaped CRTs, from a phosphor color collection point of view I should stop skipping square ones on display at those events.
@jfeng, yes, the DG7-32 CRT (green, short persistence) was used in the Marantz tuner and many other devices. Looks like Marantz liked to use CRTs in their devices because I came across a discussion to adapt the 4400 from 50TB1 to 2BP1 CRT, and there are more for sure.
