I read in the manual that if circuit revision 2, then you can use 6h30 power tubes. how can you tell what revision it is?

Hello, You can tell by simply flipping your MKIII over (be careful lol) and underneath there are holes, just take a flash light, and look around a bit, you should eventually see some like V.1 or V.2. When did you purchase your amp? You can also unscrew the amp, but I am sure you can find it just looking inside... Good luck...
