Selling a barely used PrimaLuna ProLogue Four Power Amp with brand new tubes. This was purchased for use in a second system which then became a home theater. Don't need the 2 channel amp anymore. It has about 100 hours of play time and the original tubes that are included were never used. I put NOS tubes in and stored the originals away. This is a 35 watt per channel amp with EL-34 power tubes (can also use 6550, KT88, KT90, 6L6GC, KT66, 7581, or EL37), two 12AX7 and two 12AU7. This amp uses NO NEGATIVE FEEDBACK! That makes it pretty unique and the sound is on the warm side with nice imaging. A real nice sound that really shows off your tubes. This point-to-point wired amp has some other innovative features such as Soft Start - which ramps current to the tubes instead of slamming it on, a Tube Plate Fuse - so a shorted tube will not harm the amp or speakers, Adaptive AutoBias - you don't have to match tubes! Build quality is great weighing in at 38 pounds and containing ceramic tube sockets with cooling holes at the base which draws air from the underside and allows it to flow over the power tubes. Nichicon & Realcap capacitors, WBT terminals, 20-85khz +/- .5db, S/N 89db, THD less than 1% at full power. Tube cage is removable without tools. Now the only downside, the cleaning lady put 2 dings on the right hand side that go through the paint. You can't see them from the front and they aren't that noticeable unless you know they are there. There is a faint "N" shaped light scratch on the front that I didn't notice until I started taking photos. For these scratches I am selling it at a low price of $750 which nothing at $1000 (used) can touch. Will ship in original box. I can email hi-rez pics if requested as Audiogon doesn't allow for good photos.
