Today im going to change them all to see if it works, if not. im sending it back to Marshall for repair. They just adviced me to change tubes before i send it back due to the tubes only having 6 months of warrenty.
One more Question - How can it be possible that if one tube dies, all the sound in the amp does too? Cause thats what happend. There is absolutly no sound in this amp. Do they affect eachother or how does it work?
