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?
