Stryker I am not Markind but I have done the electronics thing as long as I can remember-----------what!!?? What was I talking about, OH Yea, the POT on your 3 in 1 board. They usually come in standard sizes, 1k, 2k, 5k, 10k,...etc. You might be reading resistance values of other components in the circuit along with the POT to get the 1.65k. There is usually a marking on the pot to tell the value. If not about the only way to tell is to remove it and measure with an ohm-meter. If I were a betting man, I would guess 2k or 5k. I will have a look when I get home.
