[sylvania]

I was wondering if i did something wrong, I have a Sylvania chassis 336mu I hooked up this test CRT with yoke and anode connected brought up voltage slowly a bright spot formed on the CRT a pin sized area of phosphorous burned off in the middle pin sized i turned brightness down and shut it off. I am only getting a few pops out of speaker and no picture hooked to VCR. CRT glows and my HV is good,tubes checked ok and been recapped. I checked the test CRT for shorts and emissions tests like new.
