The manual was complete, parts list, adjustment procedures, etc. No worries

Very usefully, I could find the trouble clearly with that manual.

Bon produit. Permet de corriger les couleurs et de redonnez un petit coup de jeune à vos vieilles vidéos. On regrettera juste le manque d'une prise s-vidéo.

Quality scan of the actual service manual, just what I was looking for.

Straightforward ordering process. Service manual scan was clear & easy to read. Very comprehensive instructions for alignment. Excellent, thank you.
