beautiful and rebuilt HEATHKIT IG-72 Audio Generator$139 free ship inside continental USA

Here is a Heathkit IG-72 audio sine-wave generator, ideal for testing tube audiophile amps and guitar amps. This is a quality model that has an excellent low distortion sine wave for tube amp testing. And beautiful original cosmetics.

Rebuilt electronics, consisting of:

  • new capacitors (including correct orientation of caps regarding foil side of the caps)
  • upgraded the 5k-20W resistor to a 50W surface-mounted unit, for cool operation
  • meter smoothing capacitor
  • many resistors replaced to bring circuit into excellent overall accuracy
  • clean sine wave on all frequencies.
  • 3 wire grounded line cord installed to meet modern safety standards

I have attempted to photograph the sine wave below.  The sine wave looks better in-person than the photos show because my  camera has a tendency to bloom the scope trace.  (Photography is not my specialty!)
