Hi all,

I'm doing some work on a WPC power driver board in my STTNG and I have a resistor question.

I have found a dead 2.7K Ohm, 1/4w, 5% (R84) ceramic resistor on the board. I have a spare 7 Ball Trough Photo Transistor assembly with a working 2K Ohm, 1/4w, 5% (R5) ceramic resistor on it and I was wondering if I can use the resistor from the trough assembly on the power driver board.

I read that you can't go up in Ohms on a resistor replacement, but I was wondering about going from a 2.7k to a 2k.

I know this isn't ideal, but will it work in a pinch?

Cheers,
Greg

Bump for the electronics gurus before I drive across town to grab a $1 part.

Quoted from johnwartjr:

I would get the correct part.

Agreed. Figured it was better to be safe than sorry.
