Help: White's Blue & Gray Pro alignment and diagram !

[Robby78]

Hi !
I've a White's "Blue & Gray Pro" model that I used for a long time.
Some months ago i had a problem with my battery pack and a technician, in few words, destroyed my detector. :mad:
I don't know why he modified some connections in the PCB and moreover modified all trimmers adjustments from the original factory alignments!! He had to change the battery pack with a new one and nothing more !!
I'm really desperated for this becouse in Italy nobody can help me.
Now i want to "rebuild" all the original connections on the PCB and align all the trimmers he touched.
To do this i need the schematic and a service manual (or something of similar) that drive me in the operation.

Can anyone help me ? Waiting for your replies i thank you in advance

It's similar at the 7500 model!!.

Have you asked White's? Since they no longer sell the B&G model, they might be willing to send/sell you a service manual.

Thanks alot Carl, it is a good idea! I'll try to contact them and maybe fix the detector.
I never imagined that B&G schematics are so difficult to find...anyway for the moment any other help is wellcome !
