You know you can put resistors in series....right?

no i dont, can you tell me a conbination for 920Ohm?
Thanks

You should be able to get 680 ohm resistors... they’re very common.
Twist legs of two of them together and then put a third in series... 1,020 ohms which is likely close enough.
Or find some 68 ohm resistors, again very common, put 3 in series and then add a 680 ohm in series.. 884 ohms or, again, close enough.
Get some resistors and a multimeter and play around, man. You can figure this out.

That's not a very common value -- found in 5% or better tolerance resistors.
- 5%, 2%, and 1% tolerance values. http://www.rfcafe.com/references/electrical/resistor-values.htm
- 20% and 10% tolerance values. https://www.engineeringtoolbox.com/resistors-standard-values-d_1659.html

I thought they were supposed to be 910 ohms -- 920 ohms is a non-standard value.
A 430 ohm and a 470 ohm resistor in series add up to to 900 ohms. ;D
If you don't have the right value resistors to add up in series, there are handy parallel resistor diagrams, formulas, and calculator at https://www.engineeringtoolbox.com/resistance-serial-parallel-connections-d_1881.html.

EDIT: Not sure what the max % tolerance is for the resistors in your mod. Most common resistors are 20% or 10%.

is this the correct way to add 1k pots to the mod? green is ground,white its out, blue with 500ohm resistor is in.
