Sencore VA-62

[Kevin Kuehn]

Very impressive, Dave. Now I want to see someone do a bar sweep IF alignment on a vintage set.

They explain the Sencore bar sweep alignment method in my 1980's vintage school text book by Kiver. They're using the older VA-48 but I'm sure the process is the same. You really need to have a solid grasp on how the IF response curve works in order to relate that to what's showing up on the sets CRT. At my basic level of alignment experience, it just seems very confusing.

I have a VA-48, and also Milton Kiver's excellent book about the B&K 1077 (Television Analyzing Simplified). Can you tell me what book you have with Kiver explaining the Sencore device? Thanks.

Chris,

I was off on the year. It's a 1973 revised text that we used in school. Basically an update of the older Kiver works. If fact much of it reads the same as my 1949 edition, only this is updated for the newer sets and test equipment.

I can try to scan the VA-48 pages. I think there's about 8 pages. If interested pm me an email.

I'm with you Kevin. My 721TS is the only one I have attempted, and I never did get decent audio. I read through Phil's scan of the manual (thanks very much Phil!) and also found the Sencore VA62 burst alignment confusing. But maybe someday it will sink in to my thick skull.

Something tells me Bob probably has the burst bar sweep alignment method mastered by now. He's been very quiet.
