  What problem?

  Edit; I'm guessing that when grid current is drawn the cap will charge and then the bias will take a long time to recover?

  I think beto1's biggest problem is that his speakers are not efficient enough for a SE 300b amp.

    Tre',
    if the speaker's efficiency is related in that way with this noise, you are right. I have a 91dB speaker that sound well on a medium size listening room, but not an ideal match for a low powered SET amp.
    I must to be very honest: I am one step behind your explanations; my electronic knowledge is very limited, so with every answer opens a new path to research for me.
    regards
