How good a "sine" wave to drive a selsyn/synchro?

The simplest way to get this pair of devices working in a non-400hz 3-phase
environment seems to be to program a pic to generate three-phase and amplify
the output. If I have three pins per phase and run each through a resistor
of some calculated value I can make a psuedo-sinewave. Is this likely to
have any issues because it's not a true sinewave? This is a hobby-level
application, so good enough will be good enough....
