2. Exactly HOW do you remove a tube??? Push down and turn....twist and pull???????
I know these are very elementary questions but I don't dare risk ruining my amp until I know for sure!
Thanks in advance for the advice/education!

#1: Yes, turn off the amp first before changing the gain.
#2: With even pressure on your grip, pull the tube straight up. If it is real stubborn, while you are pulling, wiggle slightly. When you have the tubes out, it is a good idea to clean the pins gently with Deoxit or tuner cleaner. Some use a small wire brush or old tooth brush to assist getting any corrosion off of the pins. The cleaner the pins are, the better contact they have and the easier they come out the next time.

Have a good one!
