    image. So, I finally bought one. Love it. I'm completely new to the tube rolling game. I've attached a pic of the tubes I ordered to experiment with.

    What is the best way to go about this? I'm thinking: leave the ruby in v2 and start swapping out v1 to start. Or would changing out v2 make a bigger difference.

    Also, what combination of the new ones would work well together? I suppose if I had more money and was more clever it have bought pairs of each of these.

    In my PF-50T, the only one that makes any difference to my ears is V1. And I did a little tube swapping myself, with a new Tung Sol and a couple of NOS tubes, and I thought the Tung Sol and NOS tubes made it too bright and tight. But it's fun and doesn't cost much, and it's certainly less expensive than a crack bender, so have at it :D

    I would be interested to hear how that gold lion sounds compared to the others. Please keep us updated.

    I haven't really had a chance to turn it up enough to get a really good feel. It seems like it's not lacking in the warmth dept from what I can tell. It's in v1 now as a matter of fact.

    Tung sol's will brighten the tone up a bit but I always felt they were thin sounding in the lows and mids! I would go JJ's
    Be careful with the long plates some are very sensitive to vibration.

    Right now I have tube amp doctor power tubes in. Preamp tubes are gold lion v1 and a tube amp doctor. I'm really liking the way it sounds. One thing I noticed with the stock tubes is that I was hearing a sort of vibrato effect that wasn't pleasing on the lower notes. Too much of a good thing maybe. Now it's still appreciable but tightened up quite a lot. Very musical. Idk if I'm explaining it well.
