36 Watt hiss problem

Post by seanman10 »

Hi,
Just finished a 36 watt and I am having trouble with hiss.
The first problem I see is V3. Any tube I install sounds microphonic. I have tried all of my 12AX7's and T7's. I know they are not faulty.
Any ideas?
Thanks

Hi,

Are you using carbon composition resistors? They hiss like a snake.
