A local repeat customer recently brought in his old HH Scott HHS-20 receiver for an overhaul. It worked a few years ago when he put it away, although not without a few issues of its own, and when he dug it out it was right to the shop for an overhaul.
The HHS-20 was a very entry-level receiver, and not much information turned during research other than some speculation about it sharing an FM section with a bigger sibling. Inside, it used construction that would have been at home in a late-’60s early solid state receiver with a couple of odd exceptions, there’s a single PDIP-14 op-amp chip, and an assortment of TO-39-style op-amp chips in the FM IF strip.
It’s a cute little receiver with an FM MPX tuner, a tape loop, a single aux and phono input. I’d more accurately describe it as a self-propelled FM radio, more or less, because the -20 in the model number “HHS-20” represents the total power output: a maximum of 10W per channel, as measured after the repair was complete. Sensitivity measured at 150 mV LINE and 4 mV PHONO for maximum output.
