Ed,
Used the same units when we first went AM stereo in 1984. Was in use till a
new chief engineer arrived with his fancy new processor. We're now using
the Optimod 9100B-2 with the LED metering. If you do look for an optimod,
find a 9100B with the 'real' meters.
Real meters are prone to sticking.
The bar graph's react quicker and don't stick.
