They list for 9K a pair new.

Used they are in the 4500 price range per pair.

The deal I had cooking slipped away...basically the person who wants to buy my 2 MC-2102's was selling a pair of these amps off to help pay for them. I did not indicate to him soon enought that I would do a part cash part trade deal and he sold them .

A pair of those would definitely be welcome on a cold winter day. I would love to hear them hooked up to Klipsch speakers. As an aside, there was a gal closely related (can't remember if it was a daughter) that popped up on the Alfa bulletin board a while back, and people were quick to make the association of the Manley name.

Eve Anna Manley runs the company. Was married to David Manley, who split and left the company. Her dad owned Ampeg. She's only 39 or so.

They also make on of those amps with 10 KT90s. 250/500 watts. The price goes up though.

We had a forum member on here for a while who had one of thier EL84 amps. Nice.

Very interesting company. They have a link about resistors. Two types that apparently blow in tube amps if tubes blow. So Manley cooked up a scheme in which they send you snap in resistors. Pretty cool idea. The Neo 250 can use the snap in resistor scheme.

EveAnna is a real cool chick. I was showing my Stingray at one of my audio meets and she sent a big box of swag to give away. You can see my amp on there website: http://manleylabs.com/containerpages/stingray99.html Its easy to pick out. Not many homes have pink walls.


Wow! Wild-looking amp! Does it sound as interesting as it looks?
