Harman PQ-10

Nothing is documented about a Harman PQ-10. The archive's listing seems to rest on a name match from a single period source: a comparative amplifier table in Audio (May 1987, p.52) that includes a model called the PQ10. In that table the PQ10 is attributed to ADS, not Harman. It sits in the ADS column beside the Carver M.240, Hafler MA-1, and Harman/Kardon CA260. The ADS PQ10 was rated at 35 watts into 4 ohms and measured about 40. No Harman-branded PQ-10 appears anywhere in the source material, and no specifications, dates, or literature for it have surfaced.

So this page is a placeholder for a machine that may or may not have worn the Harman badge. If it did exist, the record has gone quiet. If the archive's attribution is wrong, this entry documents the confusion rather than a confirmed product.

Known from the period record:

- Only source: Audio comparison test (May 1987, p.52)

- The "PQ10" in that test appears under ADS, not Harman

- No confirmed specs, dates, or literature for a Harman PQ-10
