[TH'r]

Okay I want to try the Mr Bill Build on my Classic ID where in the world can I find the parts for this Please Help

Thank You
Jim

I found all of the parts for my modification at Mouser Electronics.

For the Classic ID Detectors

i dont mean to be stupid but what is this mod for? i mean what is its purpose? i bought my dad a new whites coinmaster classic a couple of years ago and it has no id meter and only 1 control knob that turns it on and also serves as the discriminate knob....theres no volume control...its wide open volume as soon as its turned on. i need to figure out how to add an id meter and threshold knob..
is this mod for threshold?

Took a list to radio shack of what I needed to the Mod they said they don't have any of it so now where do I turn Or should I just leave it alone buy a bigger coil ?

It is an abbreviation for a Self Adgusting Threshold ... S.A.T. appeared on a Whites Eagle SL2 That had a few years back... I miss that machine and had found alot of great treasure with it.

- SAT on either 220k or 395k resistor I didn't notice any difference,

SAT is SAT and has not a relation to the depth. if you use JFET opamps (if no so change its on JFETs) you need to operate not 100's kOhms but MEGAOhms, in the SAT. 1...2M may be good. you second mod would be an RX opamp in a coil. for that you need to open a coil and insert a board inside on manner that greedlab does it always and why wins any testing on the gives much better depth than normal.

good luck

I just finished that mod on CIIISL. In fact it's probably 4th or 5th Classic I modified that way. But first time ever with R32 mod via 2 position switch with additional 395k resistor. So, machine was set as below:
- Disc at [P],
- Freq at [low], I found that low freq gives a bit better depth on most of the targets (usually 0.5-1cm on tested objects, but on one coin was a bit worse compared to [P] setting),
- black sand mode (gives much better depth than normal),
- Sens at maximum,
- SAT on either 220k or 395k resistor I didn't notice any difference,

Results (air tests):
1 euro cent- 23.5 cm,
1 pence- 28 cm,
5 pence- 27 cm,
2 pence- 34 cm,
1 pound- 34cm,
1 euro- 35cm,
very thin gold ring 22mm diameter at 31cm,

same settings but sensitivity at 3 o'clock:

1 euro cent- 18 cm,
1 pence- 22 cm,
5 pence- 19 cm,
2 pence- 26 cm,
1 pound- 27 cm,
1 euro- 27.5 cm,
very thin gold ring 22mm diameter at 22.5 cm,

I have also modified White's Classic II SL, with R24 1.8M (instead of 2.2M in CIIISL). And results are actually exactly the same. But there is a difference in discrimination. CIISL discriminates piece of iron just above 9 o'clock when CIIISL same piece of iron, close to P setting. I had tested CIISL in field and found it to perform well after modification. But I noticed that after ground balancing it's sensitive to stones. So, I had to lower sens from max. to around 3 o'clock. Or, turn ground balance slightly anticlockwise.

jim where in the world are you ? maplins is where i got mine make a list of what you need values and such like and go ask them thats what i did and it was like painting with numbers put the right number in the right place easy if you can solder !!!!!

In Pa. USA This will be the first time I tried anything like this Thanks for the reply and info Looking for local supply co.
