For sale ROGUE AUDIO stereo ST-90 with the Silver Face which in my opinion is much better looking ???? and more attractive than the all black version also like to point out the amp was upgraded with HiFI Tuning Silver Star Fuses just on the tubes fuses section as you can see in the pictures. Overall the amp is in good used condition 7/10 some fading engraving on the back of the amp please take a look ???? at pics for reference and few marks, nicks here there but nothing major. Comes with four used Electro Harmonix KT90 not sure exactly how many hours on them and two 12AX7’s and 6SN7’s. No stock power cord is available. This tube amplifier is your way to start your tube experience if you don’t want to spend thousands of dollars ???? on a tube amplifier and to be honest with you the RA ST-90 sounds pretty damn good for the money. I was so impressive that one day I paired with my Odeon’s speakers playing big band’s and orchestra with impressive attack and dynamics! it felt like the band was in my room I played the same track ???? about six times no kidding ???? also it has that nice analog sound without any harshness, nice midrange and a nice tonal balance, with great bass. Reason for selling is cause I’m downsizing. I do have the original box, manual. Will pack with care for safe delivery but I don't have any control what FedEx or UPS handle the package ???? . Will add insurance to be in the safe side.
