:yumyum: I only changed one tube in my 5150, and it is awesome now. I replaced the stock 12AX7A in V1 with a GT 12AX7R2. AWESOME!!! Of course, I had to swap the other 4 around a littl bit until it had trhe least noise and greatest tone, but Whooooah!!! This amp will sever you ears from your head if you're not careful!! Long Live the 5150!!!
