Ashly SC 66
The Ashly SC 66 is a rack-mount mixer amplifier. It's a commercial-duty unit that appears to have been aimed at paging and distribution work in schools, churches, or retail spaces. Documentation on this model is thin, and what survives comes mostly from owner reports rather than period press. The most useful description on record calls it "an extremely well built commercial type amp," and the general consensus among those who have handled one is that it was built for installed sound rather than home hi-fi use.
The SC 66 is rated at 100 watts continuous average per channel into 4 ohms. It can be bridged for mono operation and also offers 70-volt outputs, which confirms its intended role in distributed speaker systems. Inputs are minimal: a single XLR for mic or line, plus a barrier strip for additional connections.
One owner asked for advice on a non-working example and was told it's "a bit under powered for the current world of audio." The respondent said it would still serve fine as a PA amp or for mains in a low-power home system. The catch is that 100 watts per channel doesn't go far with inefficient speakers. The same respondent noted the unit has a fan that will likely be audible in a quiet room.
Modern Recording (October 1977, p.69) covered the SC-66's flexible equalization and suggested uses including control of feedback, ring modes, and speaker cabinet resonances. The same review noted the rear panel uses standard phone jacks for left and right channel inputs and outputs.
