Krell KST-100 (c. 1990–1991)
The Krell KST-100 was a stereo power amplifier advertised in Krell's lineup from at least late 1990 through late 1991. The company's print ads of the period show it beside the KSL high-level preamplifier. The range also included the KSP-7B preamplifier, the KSA-150, and the MDA-300/MDA-500 mono differential amplifiers (Audio, October 1990, p.183). The most concrete surviving specification is in an Audio advertisement (December 1990, p.25): 100 watts per channel into 8 ohms, with the amplifier rated to drive loads as low as 1 ohm. A later Audio spread (October 1991, p.146) repeated the pairing with the KSL and noted the line was available only through authorized Krell dealers.
Beyond those advertisements, little is documented about the KST-100. The archive has no dedicated period review of it. A 1991 Audiophile report on Krell Industries noted that wave soldering minimizes unit-to-unit variation (Audiophile, 1991, p.171). No production years, original price, weight, dimensions, or circuit details are confirmed. The record does show that it was Krell's 100-watt stereo amplifier at the turn of the decade, presented in print as a companion to the KSL preamplifier.
