Hi Folks,

Very nice Heath hi-fi amp model A9C.  Works well.  Has mag phono, crystal
phono, microphone, and tuner inputs, bass and treble controls..  Output
impedance is 4, 8, 16, and 500 ohms. All tubes are original Heath-logo.  I
assume this one is late in the model run as it uses the highly rated
push-pull 6L6GC in the outputs.  All of the 12AU7 /12AX7 tubes are made for
Heath by Mullard.  I have replaced the two final-stage coupling caps and a
power resistor, otherwise all original.  $100 or best offer. The Heath
catalog says shipping weight is 23 lbs.  So add for UPS from zip 45701.



No manual but schematic is at the following and the catalog description is
on the Heath virtual museum site.
