If somebody knows what is the problem with my 1966 Aeolian Pianola,
please tell me what it is.  When I pedal without it plugged in,
it is very easy to pedal compared to when it is plugged in.
When it is plugged in, it is almost unable to pedal, doesn't work
if I don't pedal at high speed.  Thank you in advance for your help.
