Whites Coinmaster 4 - schematic?

[Frank]

I have an old Whites Coinmaster 4, been about 20 years since I last used it!
Needless to say, it fails to operate although the batteries indicate good.
Looking for some help, like a schematic. It is a CM4 and has a Coinmaster IV TR loop.
Single board unit.

I'll try to remember to look for one tomorrow.

Thanks for anything you can offer. I know its an old detector, but I sure had some good times with this. Some quick checks with a scope shows it does produce some frequency busts, though I think it showed less than 50 mV signal. The "meter" indicates negative (less than zero), and the null control has no effect. I just dread trying to shot-gun repair this board, although not alot of parts. I would guess on of the transistors went bad somewhere.

Frank,

If you haven't got a schematic for the 4 yet, send me a valid email address and I can provide you with a schematic for the 4 in PDF format.

Need Coinmaster CM 4 schematics for repair

Hope one of you can come up with a resonable schematic for repair of a Coinmaster CM 4
metal detector. I have one that has been tampered with and it has a short someplace.
I need to track it down. Looks simple but there are 2 voltages to keep track of.
Maybe someplace one of you can find something for me.
I'll post back what I find and maybe some specifics of getting an old one running.
Thanks robert_sare

I have a WEPI-1000 schematic. If that might be what you seek, send me a valid email address and I'll send a copy. It is hand drawn and I have no idea as to how accurate it is.

I see some people like deal Balamil this nasty
Who has a new project or something puts it in a forum
For it was he who taught us these things and how to make them
In the latter thank all of the staying up on this forum: (

Could I please get a copy of that schematic? Seems I'm having the same problem with my CM4.
