Hey again,

So, I'm excited to be getting a YCS50 shipped to my door within the next week. $525 shipped seemed like a good price, so I went for it... now I just need to sell my Palomino.

Anyways, my question is simple. For any of you who have or have had the YCS50, what power tubes sounded best in it? It looks like it uses two 6L6/5881's, so which should I go with? JJ? Tungsol? something else?
Also, if I get a matched set, can I just pop em in and play? I've read about an "Auto Bias Circuit" so supposedly I can, but I don't want to screw something up.

I probably won't do this for a while, but the tubes have never been changed so I will do it SOMETIME soon since I'm buying used.
