Offering my pair of Quad Classic MKII, mono tube Amplifiers.
I purchased these amp from Globe Audio Marketing in Feb 2005.
The amps do not have many hours on them and have sat idle for some time. I initially bought them to play with my LS3/5a's and Quad 57 ESL's
They are in near mint condition with the odd blemish here and there.
I recently replaced the KT66 output tubes with a fresh quad set of matched Shuguangs. Installed and tested for approximately 30 minutes only to confirm they were perfect.
These units were in current production from Germany under the banner - QUAD Musikwiedergabe GmbH, under the direction of Manfred Stein with a MSRP of $4995
Reproduction Quads made from the highest quality transformers, caps and point to point wiring/soldering by a Quad factory skilled technician!
Their design reflects a Class A, Push-Pull, Mono circuit with only two active stages and is a tribute to the original designer, Mr. Peter Walker.
These beauties are in excellent condition, conservatively rated at 8/10 c/w original boxes.

Quote from Art Dudley - Stereophile
" For its part, the new Quad II Classic is like finding a wormhole in the time-space continuum and going back to the Cavern Club of 1962. Or, to paraphrase Ken Kessler paraphrasing Quad themselves, this is the closest approach to the closest approach. Go buy a pair of these, use a bit of nail-polish remover on a cotton ball to remove the silk-screening, and live it up—life is brief, and second chances are thin on the ground."
