I have recently bought a new amp, and changed the power amp tubes. The amp is marshall tsl601 combo and it has two JJ E34L power tubes in there. Now the guy in the service hasn't biased them, and since I don't know much about that stuff, and you're an expert, I was wondering could you help me out and give me some tips how to do it myself.
So is biasing really necessary, and if it is, can I do it (i don't have any electronical knowledge except some soldering skills ).
on the amp there's a small plate just above the tubes that serves for biasing, I can give you the picture if needed.
Thanks in advance mate, I appreciate the support
