[ARC5] Lopsided modulation

    I wonder if your 1001A also had hum modulation at higher 
frequencies. Mine does and it seems to be from the magnetic field 
of the power transformer affecting the amplifier. GR made these 
things for a couple of decades. Very definitely has asymmetrical 
sidebands.  It was a cheaper generator (and lighter) than the 
805B/C which has excellent modulation but weighs over 100 lbs.
