About this model

The SQ38 is Luxman's long-running integrated tube amplifier line. Japanese sources date the SQ38FD to 1970 and the Mark II revision to 1974, matching the seller's statement that this unit was all original from 1974. Its output tubes are 50CA10 triodes, a type Luxman had made for it by NEC; Phile-web notes there is no direct replacement, and a later Chinese reissue has largely sold out. That makes the seller's mention of NOS NEC tubes inside, plus the original Luxman set, a real point of value.

The 38 series is generally rated around 30 watts per channel, but we have not found a primary document giving the Mark II's figure, so we leave it out of the table. The seller also offered an external transformer for 115 and 230 volt countries.
