Conrad Johnson Premier 12 Glorious!

For sale a pair of Conrad Johnson's classic Premier Twelve monoblocks rated at 140 watts/channel into 8 ohms.  These amps truly sing - lush, detailed, powerful, and - perhaps most important - alive with energy.  I bought them a couple years ago and would happily hold onto them, but space constraints force me to let them go. 

The amps were serviced by Conrad Johnson in Fairfax, Virginia in July 2013.  On handing the amps back over to me, the technician said they were good to go "for the next 15-20 years."  There are two scuffs on the black paint on the capacitor of one amp that were there when I got them, and unfortunately no cages - otherwise the amps are cosmetically and functionally perfect.  I have the original manual, biasing tool, and new boxes and packing material from Conrad Johnson. 

Consecutive serial numbers 6101211 and 6101212.

Included is a set of eight matched Tung Sol KT 120s from Upscale Audio that have about 400 hours on them, four brand new Mazda 6FQ7s (also from Upscale Audio), and GE 5751s.  At my asking price I'll also include my small collection of alternative new old stock 6FQ7s and 5751s (Sylvania, RCA, etc.), so you can roll to your heart's content.

Buyer pays shipping and Paypal.  Lowball offers will be politely ignored. 

From Stereophile's 1999 review:

"It doesn't take long to hear why the Premier Twelve remains popular,
and why so many audiophiles continue to be willing to spend $7k on a
pair when more powerful, less expensive alternatives abound.  If
designing and "voicing" an amp is a high-wire act, the Premier Twelve
crossed the Grand Canyon barely breaking a sweat. The overall sound... was finely detailed yet rich, open, and transparent, with a lush,
mesmerizing midband; deep, well-developed, yet punchy bass; and high
frequencies that were fast and sparkly but never bright or aggressive.

The difficult transitions between the frequency extremes and the
midrange were carefully accomplished, though the upper midrange
exhibited a rich, golden bloom—a sonic bouquet—too subtle to be called a
coloration but sufficiently pronounced to enrich brass, strings, female
voices, alto sax, and hall ambience with an intoxicating glow.

The Premier Twelve sounded "fast" and rhythmically taut throughout the
musical bandwidth—and with all kinds of music. It was the "snappiest,"
most coherent performance from a lush-sounding tube amp I've heard in my
system....

The Twelves always sounded confident and in control—tonally, spatially,
and temporally—particularly at the frequency extremes. On the bottom,
both acoustic and electric bass sounded tight yet supple, and totally
"in character" tonally. On top, the Twelve's transient performance was
faultless, portraying cymbal crashes with the crisp, splashy shimmer you
hear live. On good recordings, strings bristled with energy, yet never
sounded hard or unnaturally edgy.

Along with exemplary top-to-bottom
"attack," the Premier Twelve portrayed decay with equal propriety,
resolving low-level information that, before disappearing into the
ether, seemed to travel farther in space and time than I've experienced
with other amplifiers. The combination of fast attack and slow decay
gave the Twelve a sense of limitless resolution and luxury, suffusing
the sound with an overwhelming sensation of musical authority."
