I have a circuit that puts out 0 - 5 volts to drive a meter. However the
meter I want to use accepts 0 - 10 volts. The response is linear, so if
I could just double the voltage, I could make this work. Any simple
devices or circuit that can accomplish this? Thanks, Scott.

A different meter. Sorry, I couldn't resist.

If you have a 12V supply handy you could use an op-amp to amplify the
0-5V by 2. You'd need one op-amp, a bypass cap or two, and two
equal-value resistors. This is an easy circuit and should be in any
ARRL Handbook after 1970 or so. Even one of those "Engineers
Mini-Notebooks" from Rat-Shack should do, if there's one on op-amps.
