Re: Where's a good place to buy tubes online?
Another vote for Bob at Eurotubes.
He does only sell JJ's but he listens to what you want tonally and cherry picks from what he has. Alot of other places just sell tubes; Bob actually knows the characteristics of the amps they're going into, listens to you describe how you would like the amp to sound and hand picks tubes from his stock that will give the amp those characteristics.
I've bought from Bob twice. I wouldn't hesitate to do it again.
