coiltek regulator 6.7volt to ??

[Righteous]

When i had a gp 3000 i purchased this coiltek 6.7 volt regulator.
I was going to sell it on ebay but i have now decided that i could just convert this to 7.4 volt or 8.5 volt.
A person at coiltek told me that 7.4 volt was the maximum
Ismael Jones from www.minelabmods.com.au
Had a regulator system that goes from 6.9 to 8.5 volts
So i gather 8.5 would be fine.
Is this correct?
Any comment will be appreciated
Thanks Righteous

Change the resistor that connects from the set pin to gnd for a higher value, do not under any circumstances run the detector at more than 8.5 volts. 7-7.5 gives a great improvement. Older detectors like the SD2000 like 8 volts and it makes a big depth difference.

Hi Unregistered
thankyou for your reply and letting me know which resistor to change.
All the best

8.5 volts is fine on the SD2000 but not on the GP3500 max I would use on the 3500 is 7.2 volts its internaly regulated so is no advantage to run higher voltage . Regards Ian.

Thanks for your input IBGold
Yes i never specified what detector it was for,this must be very frustrating for some people,sorry everyone.
It is to be used for a SD2000
The regulator is now running at 8.5 Volts and here it is.
Thanks again for all your help.
