Thanks LLC, yes I am getting 68k and 34k ohms now measuring as you described. Now to check the output tube bias voltage. With no tubes installed, I measured between the tube grid (pin 5 on 6v6) and ground. Does it sound like I am measuring this wrong? I get an dc voltage of 0v. Shouldn't it be around negative 30-60 vdc? On a different note, is it really necessary to develop the capacitors with a lightbulb limiter? How much of a difference does it make than to not use one?
