New valves

Ray

So what's the drill? Do I pop out the old ones and go off to Mr Valve and say gimme some new ones of these? and then go home and pop the new ones in and toss the old ones away? Just thinking that maybe I should put new ones in the Laney Cub and the Super Champ XD.

Thanks - Ray

If this has not been answered in a couple of hours, I'll go through the schematics quickly but my first guess is that neither of those amps needs a bias adjustment - if they don't you can do as described. If they do need adjusting you take the whole thing with and ask them to do it; make them set it to the same current that it does at the moment.
