Luxman leaflet for the 1998 Japanese market reissue :

"Released in 1964, the original SQ-38D became so popular that at the time it was synonymous with hi-fi amps. 12AX7 and 12AU7 tubes are used in the first and driver stages respectively. Output tubes are 6BQ5 [6RA8 originally], while the power transformer is OY-14 type.
The number of inputs is increased to five to accomodate a greater number of sources available today, but the functions and basic design are the same as the original masterpiece."

The SQ-38Ds is a slightly later version which accomodated low-output MM catridges ; the backplate name remained the same, though. The Luxman SQ-38D sold in enormous quantities in Japan and is therefore very easy to find. Still rather expensive, alas, at about 2000€, whether the original or the 1998 reissue.
Does anyone know who designed the SQ-38D and its WZ-30 tuner companion ?

See a 1960s original SQ-38D here at hifi-do,
and a 1998 reissue still at hifi-do.

Soon more images and detailed description of this masterpiece within the TVK v2 !
