Unfortunately to be able to afford rent I have to let my Stratus go. Due to the volume of tubes I have for it I'm going to post this as a base price with duplicates of the one of the rectifier and power tubes I have plus 2a3s as the "stock package" and if you want extra tubes, we'll discuss that. Version is a V2 with the choke upgrade.Full list of tubes available:2A3:Shuguang 2A3C-T Natural SoundRectifier:GEC U52 (yes, that holy grail U52). Its branded Cossor but I asked the resident tube expert Gibosi and he said"You are correct in thinking it is not a Cossor. While the pictures aren't great, it certainly looks like a GEC U52.And you are also correct in thinking that Cossor didn't make the U52. Legally, GEC owned the name "U52" so they were the only company that could use that label. And Cossor owned the name "53KU", and so in the same way, they were the only company that could use that label. These tubes are almost identical, electrically, and back in the day, they were considered interchangeable in most applications. So I am surprised that the U52 is OK in the Stratus, but the 53KU is not...."RCA 5R4GY2 RCA 5U4GBKen Rad VT244Brimar 5R4GYDriver:Cryoset 6N1P (2)Pearl Cryo Reflektor 6N1PMullard 6BQ7Westinghouse 6BQ7 (2)Brimar 6BQ7Purchased from this listing here this amp obviously doesn't need any introduction: https://www.head-fi.org/threads/dna-stratus-in-excellent-condition-with-upgraded-tubes.807896/ In terms of trades, I'd be interested in trading for a EC ZDT Jr Massdrop on the condition that it has no hum plus cash or a Shortest Way51Buyer covers paypal.
