SOLD: SinglePower Extreme (fixed)

  1. jeremyzone
    First of all, everyone interested in a Singlepower amp needs to read the following threads:
    http://www.head-fi.org/forum/thread/333677/where-is-singlepower-where-is-mikhail
    http://www.head-fi.org/forum/thread/437344/my-singlepower-supra-experience-why-mine-almost-blew-up-like-a-hand-grenade-and-yours-might-too

    Up for sale is my SInglepower Extreme amp. I bought this amp from nurxhunter in the following thread:
    http://www.head-fi.org/forum/thread/478975/withdrawn-singlepower-extreme-fixed#post_6497791
    The above thread details the changes and fixes that have been done on this amp to increase its safety. The overview of this amp is that it was a stock Extreme (no modifications made by Mikhail) that nurxhunter took to a tech. The tech added a second transformer to deal with the underspec stock transformer, bypassed the R54 resistors to bump up the heater voltage from 5.7 V to 6.1 V, and installed an in-rush current limiter. That being said, there is always a small amount of risk associated with SinglePower amps. Personally, I have noticed no problems with this amp. It is certainly a warm amp, but I can put my hand on it after a few hours of running it without burning myself. It sounds GREAT, which is one of the best benefits of owning this amp.
     
    I will include the following tubes as well as the Singlepower ECC #1 adapter:
    Output tubes: 3 RCA 6AS7G (I think that 2 of these make some faint crackling noises, which are noticeable without music playing)(the previous owner is providing 2 used but testing as NOS Raytheon 6AS7G to replace the 2 tubes that failed), 2 Raytheon 6080, 2 RCA 6080
    -Driver tubes: RCA 6SN7GTB, RCA 6SN7GT, Motorola 6SN7GTA, CBS Hytron 6SN7GT, Sylvania JAN 6SN7GT, GE 6SN7GTB
    -Driver tubes with ECC #1 adapter: Raytheon 5670, Sylvania 5670
     
    I will also include the power cable, but all other cables will not be included. I will throw in my unused Deoxit and Deoxit Gold so that you can clean up the tube pins.
     
    I'm looking to keep this within the US. I'm asking $SOLD for everything, which includes shipping. Payment by Paypal. Please PM for questions.
     
    Here are pictures of the unit. The last 5 pictures are from the previous owner, including pictures of the internals.
