Hi Folks,
I need some advice re: tube matching. I have just finished an amp based on the Dynaco 70. So, 2 x EL34 output tubes for each channel. I am currently using JJ tubes but I was thinking of upgrading to some NOS Mullards.
This is a silly and basic question I guess but what happens if the tubes (I am just talking about one channel now) are not matched? Is it a major problem or just a theoretical issue? I am totally ignorant concerning tube matching. The Dynaco circuit has bias pots - does this make a difference?
Thanks in advance,
Rob
