Before going to the eplace... For sale: 
Heathkit IM-22 Audio Analyzer 

The IM-22 contains three instruments in one: 
an AC VTVM, an audio power meter and an 
Intermodulation Distortion Meter. The unit 
is tube based and except for the color scheme 
is very similar to the AA-1 and IM-48 Audio 
Analyzers. For pictures and specs, see page 
32 of the Heath 1963 catalog at:

http://www.tech-systems-labs.com/pdf-files/heath-1963.pdf

I bought this analyzer a few years ago and 
went over it with a fine tooth comb. Every 
component was tested and, if not up to 
spec, was either repaired or replaced -- 
including all 1% precision resistors, caps, 
tubes etc., even the line cord. Since then, 
it has been in use, but infrequently 

I have just checked it and touched up the 
calibration. Everything is in excellent 
working order. 

Cosmetically, it's way better than average. 
The front panel is in pristine condition, 
the meter cover is shiny -- no scratche or 
scuff marks at all on either. The case was 
painted (same color, same texture as the 
original) and still looks great. All knob 
inserts are clean, etc., etc.. I'll be 
happy to email pictures -- just ask.

In short, this instrument is suitable for 
both actual lab use and as a Heathkit 
collector item. 

Asking $65 plus actual shipping for 15 lb. 
from zip 01702 (please look it up on the 
UPS web site). No test leads, but I will 
include a complete copy of the manual (an 
$18 item by itself).
