Up for sale is a SE 274B. I purchased end of March of this year. It replaced my NOS JAN RCA 5R4U GY which was very good. This was a step up in bottom and top end. Resolution and bass are very good. This is in my Lampizator DAC. I have too many rectifiers and moving to a good home.

Price includes shipping CONUS and PP. I also accept Venmo.
