About 16-17mA, can be more or less.
does this means that using batteries is possible ?

Yes, but normal 9V batteries won't last very long.

You could use some 1ah batteries setup so when you turn the buffer off it turns the charger on.

Circular holes are the most benign, so the pins aren't too bad. In most cases, perforations probably don't cause problems for audio unless there is a grounding mistake. But I figure, if it has a ground plane, why not go all the way? In any case, I was able to widen the solder rings.

I've also added some random solder pads for those that might want to add stuff, as well as a pad for one of the screws if you want to connect the board to chassis (sometimes there are reasons for doing so).

I'm close to getting this printed.

If the 550 and 560 outline to pad position/size ratios are accurate reps of the real parts wouldn't it be good to move them closer together so there's no need to bend leads to have them touching?

Same thoughts as I had, but then the text wouldn't fit or would be too small to read. Also there are traces running between them that need space. So I could move them closer but not by much.

Are all pads NC? A pad for ground would be nice for 100nf caps to chassis. I run mine with a cap to chassis because my enclosure has too many small openings. The sound is much smoother with it.

I'd like to see it at half the size.

Oh well, it's easy to back seat drive, I'll shut up and leave you to it. I think I can manage shaping a lead or two

Going through the thread in spurts, I haven't seen a drawing with the 431's in. Do you have one to post or is that part of the circuit still evolving? Just curious.

Thanks
