    Valve recommendation please.

    Hi.
    As some of you know, I've gone from all Solid State, to all valve, and am now currently in the Hybrid stage

    I've recently picked up a used Unison Research Unico Hybrid amp, that uses ECC82 (12au7) valves in the pre and a MOSFET power stage.

    I really like the overall sound.
    I've taken out the original Jan Philips tubes, and put in some Brimars.

    The mid and treble are great , really lovely, but the bass is a little over heavy.

    Is there a tube that will keep the mid and treble as it is , but lighten up the bass a tad?

    Cheers.

    Mullards.

    Lovely amp the Unico. I swapped out the stock ones for a pair of late logo NOS Mullards which made it sound even better, and never felt tempted to change valves again.

     Yes
    Here you go. Any of those would be worth the candle, especially the Mullards.

    Telefunken if NOS.
    If you're looking at new valves then Shuguang Psvane or TJ Full Music (Psvanes have a full bodied, lusher sound than the TJs).
