Fisher 1266x

[eduardo1979]

Hello! I have bought a Fisher 1266X of the second hand and the fact that tape-worm before the detector, it has opened and turned all the potenciometros of the electronic circuit. If someone can help me with a photo of the original circuit to see the previous condition of the potenciometros. Thank you very much! Regards!

If i understand; you are saying that trimmers are mistuned at you 1266?
Therefore, you expect to achieve same adjustments if adjust your trimmers to be exactly positioned as trimmers on photo? Right?
If so than you are wrong. Trimmers positions are not uniform. Each machine need own, unique trimming, case by case.
Best way to retrieve factory settings is to adjust it by given procedure. You don't need any photo.
Qiaozhi once posted proper adjusting procedure, on these forums. Right now i don't remember exactly where. You must search forums here. What should be the keyword to search? Don't have clue!
Maybe you should list all the posts from Qiaozhi and read one by one. Lot of reading, but finally you will solve your problem.
Give a try.
Regards!

turn the trimmers in middle position... begin to test in disc mode... get a result... if you have o-scope there were been huge bunch of diagramms from Sean Goddart...
