Great sounding Unison Research S6 for sale!
It is in good condition. There are a few scratches that I found, please look at the pictures.
This is a class A integrated tube amplifier. It utilizes 6 EL34 tubes, 3 in parallel for each channel. 35 Watts per Channel at 4 ohms or 8 ohms. They sound fantastic driving Sonus faber Cremona. It had absolutely no problem driving it. It also sounded very nice with Vienna Acoustic Strauss. This amplifier has a beguiling midrange, and class A 35 watts is no slouch in driving power.
I can ship at buyer's expanse. Buyer pays the PayPal fee. Thank you and please ask any questions!
PS: I will also include extra tubes:
They came originally with 6 of Electro Harmonix el34 tubes, but I bought and changed with 6 of Tung-sol el34 and sounds better. I will include both sets.
They require a pair of 12au7 tubes. I have tried Amperex Bugle Boy 12au7, RCA 12au7, Mazda 12au7, GE USAF 12au7, and Mullard 12au7. With my setting, Amperex sounded best, but I believe it will be system dependent, and I will include all 5 sets of 12au7 tubes mentioned above.
The tubes that I am including are worth around or more than $600. I will include all of them with the amplifier.
