|Dave H||Re: Fixed bias supply for el84's?|
If the bias tap is 45V RMS try changing the 6k8 to 33k and the 10k to 22k. Spice tells me this will give a bias voltage range of –10V to –22V. I’d also change the 50u cap to 22u to make sure the bias supply reaches full voltage before the EL84 heaters are warmed up. If you want to see the Spice plots I’ll post them on my web site.
