Looks alright with a quick check. But a couple of questions What are the resistors from the input (I assume) the seem to be between the input and the pot? Also I would not earth like that. I would take both 0v from teh phono input, to the star point you have on the left of the amp, then take a wire ...

Yep, thats another anode follower Clive has posted. Yes, Andrew, the CF is low output impedance. So thats another choice for you. One of the advantages of the AF though, is the valve cathode can be near 0v as normal, so you don't need an additional cap on the input as the input sums to a virtual ear...

Thats exactly what I intend to do with the Slagle AVC (which is waiting for me to pay the inport duty at the moemnt, so should be heare tomorrow). I intend to use that d3a anode follower I had at Witham to drive the autoformer, and see how that goes. The AF I built with d3a has just less than unity ...

It means that unlike a normal transformer where there is galvanic isolation between the primary and secondary, a autoformer is connected to the incoming mains. Lets say for example, you connect the 0v rail of your power suppy to the signal ground of your amplifier (as is normal). Then you wire the m...

Yep, I have consistently (at least twice) seen this happen, the addition of a small resistor and then a cap makes the reg sound much better. But then of course the cap becomes important. No free lunch :-( EDIT: I miseed out the important thging, the small resistor. I am using a R22 on the 6c33c, and...
