One other thing to check is your line voltage. Ours recently changed from 117 to 125, and I had to change the bias resistor to compensate.
Your EL34's bias ok, so maybe this is not the issue, but it's worth checking.
I just made a bucking transformer to bring the line voltage back down to 110. Now the bias voltage is a lot lower.
