Ever since Ed "SRT King" Savinon took his back, I've been looking for one of these. A Krell KRC-HR pre amp (late 90's). Since Mark Levinson no32's are scarce and very pricey, this will have to do. This is a one owner pre and it is in fine shape. This is a later build with rounded edge face plate, the earlier ones had squared edges. It has been recapped by Krell. The Krell KRC-HR with external power supply is still a highly regarded pre amp. It made the Stereophile Class A recommended list. The Krell KRC and its variants used either a motorized Spectrol or P&G potentiometer volume control. The HR is equipped with a R2R (resistor) Ladder Network volume control. It has two gain stages. This one was equipped with a Krell Reference MC phono stage. It has four selectable gain stages from 58dB to 76dB of gain. Now I have remote capability; no more getting up to change volume when I play vinyl.
