Default Re: Contemplated PCL86 push-pull home brew stereo amplifier

For pentodes, the optimal load is very close to the DC resistance of the tube reckoned as Ebb/Ib, not confuse with the anode resistance, several times larger. In place of alter the DC voltage to an abnormal or suboptimal value you can combine speaker impedances to reflect into the tube plate the above DC resistance seggested.
