There's a GREAT book by Robert L. Goodman titled "Practical TV Troubleshooting Using a Video Analyzer", which was written entirely around the Sencore VA48 (simply the earlier version of the VA62). It has over 300 pages of EXTREMELY detailed information of pretty much every aspect of TV repair that exploits every possible use of these analyzers - including TV schematics, test points, alignment information, use of patterns, etc. It puts the Sencore manuals to shame, even though they are also excellent. This is one book you really want to find if you have the VA48 or VA62.
I have two VA62's and one VA48, also four VC93's. Waiting for a tri-state buffer chip to fix the digital meter function on one of my VA62's which originally had 3 separate problems.
