Hi all,
I just finished my first La2a (i plan to make 4 of them ^^)...but i have an issue regarding a self noise..
I made some test by removing tubes..and it seems the noise is at a normal level when the 12BH7 is not connected. Also, even without the 12BH7, everything works on the la2a, so i would like to know the exact role of that 12bh7.. the noise is not related to the gain control...maybe the heaters ? I really do not know since it is my forst p2p build.. Thank you for your advices.
