Smile biggest direct view CRT B&W (30 inch) ever made
Was surfing around and found this web page (earlytelevision) about a DuMont B&W TV that has a 30 inch CRT. click here

I've heard that CRTs using a big cone of metal and a glass face plate tended to fail often. Yes? Also, does the very high voltage get applied to that metal cone? Nice shock hazard for the repairman... The 30BP4 wants 22KV.

30 inch CRTs, this one a 30BP4 must have been really expensive.
