Accuphase 100-W
Not much information survives on the Accuphase 100-W. The name shows up in period equipment directories as part of the Accuphase A-100 entry, described as a “100-W Mono Amplifier.” Whether the two names refer to the same chassis or to different models isn't confirmed by any surviving documentation. The design was Class A, with 16 transistors, 44 FETs, 10 ICs, and 44 diodes, plus a front-panel power level meter. Dimensions were 18.25 × 9.5 × 21.75 inches. Weight was given as 125.7 lbs. The listed price in 1996 was $19,995. Past these directory listings, no reviews, production years, or other documentation have been located.
There are no manuals, no marketing materials and no service literature. So it's possible that “100-W” was shorthand or a tentative name for the A-100, or a variant that never reached full production. The archive treats this entry as minimally documented until period evidence turns up to clarify what it was.
