For Sale: This is a kit I built myself in 1975. It
still works well & comes in a nice woodgrain case.
Itís designed to be added to the speaker
connections of either a 2 or 4 channel System.
(This was before the days of 5 and 7 channel
systems). The range is 20 hz to 20 khz which is
the total range that only people with very good
hearing can pick up. It also contains an audio
oscillator & can perform many tests on your system
& you can see them all on the scope. It comes with
the full original manual & I donít know of any
other instrument quite like this. Itís 18.5Ē wide
x 5 1/8Ē high x 13.5Ē deep & weighs 15 lbs. This
had an intermittent display problem in 2001, but
was repaired & checked by a friend who services
old equipment. This is a collectorís item, but
also still very useable. Price not including
shipping is $125.00.
