[Amps] linears and generators

A while ago I used a modest 12v power supply with a "small generator". It
buzzed and hummed a bit which got me thinking and eventually I put a 'scope
on the generator output. Any resemblance to a sine wave would have been a
coincidence!

While we are on the subject, do you check your generator with a true rms 
meter?  Some small generators I have had to use have more of  a triangular 
waveform and 'ordinary' meters are not calibrated for that.

I understand that it is important for heaters in particular to run at the 
correct voltage, preferably within a few percent, which is not easy from 
small generators operating into a widely fluctuating load.

Does it bother anyone?
