Does anyone know what the bias reading is supposed to be on a KT88 in my RM100? Also, can I bias the tubes without a cab plugged in or will that damage it?

I'm pretty sure you technically could bias your tubes without speakers hooked up. You're supposed to do it with the Volume turned all the way down. As long as you're not trying to send a signal to a speaker it wont damage your amp. Even if you did send a signal out, I'm pretty sure nothing is gonna blow up. Someone like Rob should hopefully chime in here, but I think the transformer will be damaged if you repeatedly send a signal out with no load. I don't think 1 time or even 5 times will do it. Unless you have it maxed volume and are hammering on the Low E for several minutes. I'm not positive, but I'm pretty sure I'm right about this.

I see that. Sorry, I think we were all writing responses at the same time, lol. Your answer wasn't posted yet.
I too looked @ the manual, but it didn't say anything about KT88's - good to know they can be biased like 6550's. Makes sense...
