Trimmer pots and resistance values

Hi, Max. I kind of wish you'd have given some more information on the circuit, and how your trimmer is being used.

Anyway, there are a number of things you can do. First, 2K is actually very common for trimmers -- check the Digi-Key catalog. Since many pots are rated at +/-20%, the high end of the tolerance might be close enough. You might want to try it.

Another thing you can do if it's being used as a voltage divider is to put a 5.6K 5% resistor across the legs of the pot. The total leg-to-leg resistance will then be almost 1.5K, and the wiper will scroll across the right voltage range.

I need to get hold of a 1.5K trimmer pot for an old arcade game monitor but cannot find one of this value anywhere. Seeing as it's essential that I use 1.5K but the closest that I can find is 1K or

well... mouser doesn't carry that pot... 1k's and 2k's... but digikey has several 1.5k pot's... you will have to pick the wattage...

Thanks. I should have said that all three pins of the pot are used so I assume that makes the pot value even more critical?

Thanks, I'll have a look. :)

Excellent, many thanks. :)
