Stick that in series with a 3.3kohm resistor, and see whether you have any further luck. You could conceivably stick the variable resistor in parallel with a fixed resistor (say 8.2kohm) and combine the pair with a 3.3kohm series resistor, but that is getting a bit more refined. You may even need a 1% value resistor. Just my NZ$0.02 worth... (Post 128) Regards, BrickViking HP-50g |Casio fx-9750G+ |Casio fx-9750GII (SH4a) |
