Ohm 20-DB (Years not documented)
Very little is documented about the Ohm 20-DB. The verified research file for this model is nearly empty. It has no product type beyond "audio," no production years, no specifications, and no design or sales history.
The period-review corpus holds two OCR fragments that can't be confidently tied to the 20-DB. A spec block filed under "AMPLIFIERS" in HI-Fi-Stereo-Buyers (1978, p.44) lists a component with response to 20 kHz ±0.25 dB, 0.01% IM distortion, -101 dB noise, and a $650 price - but the surviving text never names the model. A later fragment in the same publication (1983, p.171) describes buffered inputs and outputs, switchable positive/negative phase, stereo-bridging outputs, and Bessel filter options. It doesn't identify the unit either. These fragments may be the 20-DB, or they may be unrelated listings that OCR misfiled.
This page is a placeholder because the facts aren't there. If you own an Ohm 20-DB, or have a brochure, manual, or period review that names it, the Archive would welcome the missing facts.
