Krell's first bipolar output device pre-amp, internal phonostage external PSU, (not pictured). This has just been completely overhauled. Front end gain stage transistors were replaced in the phonostage and the PSU, phonostage and pre-amp section have all been completely recapped. So this pre-amp sounds like the day it was born. Cosmetically it's in excellent condition and electrically it is perfect. The 7b was the first Krell pre-amp to use bipolar output devices. With a switchable MM/MC phonostage of legendary quality and switchable for loading and gain, as well as a dual regulated external power supply it exceeded the performance of Krell's previous pre-amp designs. It provides insight, delicacy and detail from any recording and digs downs to deliver the deepest bass. Truly an iron fist in a velvet glove. Only selling it because I went integrated for a RC volume control. £800 + delivery (currently on the bay for 850) More pics on request.
