How are modders doing the dual Discrimination mod on Tesoros?

[Pinpoint]

I found this very interesting after seeing this:

(I have PM'd the above modder, but haven't gotten a reply yet.)

That above link includes a Cibola modded with dual discrimination. Although I don't own a Cibola (would like to get one), I figure this could be done on other Tesoro models, the Tejon comes with this feature.

Does anyone here know how this is done? I'm thinking of trying this on my Compadre.

From the photos. it doesn't look like he's added another DISC channel, so I would surmise that it's simply a second DISC pot. The DISC1/DISC2 switch then allows you to change from one disc setting to the other. This would be exactly the same as turning the DISC pot be hand to change between the two settings. A switch just makes it easier.

Ahh, that's much simpler than I thought. Clever though. What would happen if you change the wire on the turn pot from CW to CCW? Would you get reverse discrimination?

Have to ask.

No - that would just reverse the DISC pot setting so that you would have minimum DISC at the other end.
To do what you're suggesting would require the DISC channel output to be inverted.

Here's the diagram for using two pots with toggle switch

I used to do this mod as Pulsar many years ago, it was quite popular. Looks like someone has got hold of one of the machines I modded and copied it

Hi,
I actually figured that mod out by myself about 8-9 years ago when i mod'd my Tesoro Silver Sabre Umax to be similar to the Tejon. Wish i saw your mod on this years ago, would have saved me the trouble figuring it out being a newbie at electronics.

Thanks guys, well done to those who have done the mod.
