Re: [ATM] synchronous motor and cheap inverter - tests and question.

How slightly would that be?
There may not be a crystal at all, in which case it probably is easier to 
make the frequency variable. There may even already be a trimmer resistor in 
the circuit as it is.
Do you have a diagram of the electrical circuit?
