I would guess that, if this tube is used only for the reverb, you wouldn't have any problem taking it out. I'm not sure though, I'd call Soldano and ask.

Not sure, but I can tell you that when I've had the chassis out of the cabinet in order to access the bias potentiometer I forgot about the fact that I was running it without the two cables from the tank plugged into the head. I have run it this way numerous times for hours at a time and have had no problems.

Are you hearing reverb even though you have reverb set at 0 or something?

Sorry man, I hadn't visited here until now... to answer your question...
When I asked him Mike Soldano told me that they bias the power tubes basically as cold as possible because they do not want to power tubes to do anything to the preamp's sound but cleanly amplify it. This seems weird to me, but it is what Mike said.

I decided to bias it hotter because I wanted to hear power tube distortion. I would not recommend doing it th eway I did unless you are okay with sacrificing one set of tubes to experimenting. I did it by ear, but also used a multimeter so I could write down he bias voltage values as I hunted around for the sound I liked. That voltage is the bias voltage- a negative voltage between -17.80 and -7.00... this is not the number you need to do it correctly... you need a Webber Bias Rite for that. After all my experimenting I decided that I don't like the power tubes to flab it up by distorting much, same as Mike... so it makes a little more sense to me now, but I definitly like it a little hotter than "as cold as possible" as it comes from the factory.
I have the bias voltage way down at -15.65 if I remember right.

My astroverb is a head and all I did was remove the four screws on the top and slide the chassis out.

When you buy JJ tubes from Bob at Eurotubes you can tell him what type of amp and he will send you tubes graded at a value that will work well with the factory bias setting. If you want to bias hotter than factory you need a biasing tool. Unless you want to risk it like I did smiley
