I was finally delivered this set I won on ebay by my kind buddy in dearborn. It looks like someone sprayed it black a very long time ago. There is overspray on the tube chart. So I guess I will strip it and see what is underneath. It looks cool in black tho. Did any come in black?
I hooked up the beltron to the 8bp4 crt and after a test and a cleaning I get around 90 after a count to 6. And it holds for close to a ten count when the interrupt switch it pressed. When I cleaned it, the light went out when reduced to 6.3. So I am thinking my tube is probably pretty good even though according to the Beltron instructions if the light goes out when reduced to 6.3 to rejuvinate. I would rather not rejuvinate this tube and risk crt death.

Do these readings jive with anybody's crts?
