I am the original owner for this amp. Barely used. Mint condition. anew price sell for $8,299.00 at Upscale Audio).This unit sell for $3,950.00Shipping & insurance is varies based on buyers location.Please contact seller before you purchase,Sale is Final. No return.

A couple of years ago i bought a second-hand Manley stingray, the seller gave me a dozen of spare unmarked Raytheon 6414 tubes.The only info that i have is that the tubes were purchased direct from USA and that they are new old stock from a computer company.The inner construction is identical with any marked Raytheon 6414 tube.The tubes are tested on my amplifier and they are functioning like they should. I don´t have any tube tester and i have no idea over their values.I am selling 4 Pieces as Used.For any questions please feel free to ask.

Manley Laboratories Stingray EL84 Integrated Valve Amplifier This interesting and great sounding amplifier is in particularly good condition, and importantly is the more desirable later improved version with Triode/Ultra Linear switching, Subwoofer out etc. Please see manufacturers note below. It was fully serviced and had all the valves replaced with new ones a couple of years a go (invoice available).It has hardly been used since. I would estimate less than 20 hours playing and then carefully stored away in its box. Whilst being serviced the optional Manley supplied Adjustable Master Bias Board was professionally fitted, to allow use of Russian EL84 valves. Please see manufacturers note below.

The Adjustable Master Bias Board is available from our Service Department to replace the 6K8 Master Bias Resistor located next to the right channel B+ fuse. The Adjustable Master Bias Board contains a 10K trimpot in parallel with a 10K resistor, in series with a 3K57 resistor. Installation instructions will be given by the service department when you order the board (if you are installing it yourself.) You need to be able to solder. If you do not work on your own amps, then you can book your Stingray with Paul in our Service Department to have this board installed for you. After installation: For Russian EL84M/6?14?-EB, set the Master Bias Trimpot to number 10 on its dial and check each tube to be sure it can bias up to 300mV reading on the bias points. (Some Russian EL84s are too low to work, and dont draw enough current by birth, so select another one that draws more current.) Reset all individual bias pots to get a bias voltage reading of 250mV on each test point.
