Hi all, I recently purchased a used Super Sonic combo amp. Someone has removed the tube chart from inside the amp. I know what kind of tubes it has, but don't know the tube layout. I'd like to change some of the tubes like I've read about elsewhere in the forum but want to pull the right ones. Thanks in advance for the information!
