    I’m using these in a Primaluna Prologue preamp. I’ve been quite impressed with these tubes, good balance and a clean sound. They were kinda bright to start but opened up after about 10-15 hours. Excellent value for the money, Get em while you can. Very quiet and no microphony. Most test with close triode balance as well.

    Quiet, nice sounding tube.

    Crisp, clear and linear, much like my Telefunken’s. Possibly a little bright but I’m using them with my Gold Lion KT77’s in a PrimaLuna Dialogue HP integrated. Probably a better match with my Tung-sol 7581A’s which tend not to have as much high frequency extention but are fantastic tubes with the PL.

    This is a little known brand that is surprisingly good.

    I am using Rft ecc82 in my mic preamp (dbx 376).. replaced by original electro-harmonix…
    I have tested many tubes over the past 5 years, including amperex(bugle boy), RCA, Tesla 802s, Mullard, Northern-Electric…
    Rft is the best…i give up testing Ecc82/12au7 tubes 🙂
