He seems to be doing it too often these days which is a problem. For us!Once Joshua says good word about something, I take it seriously.

+1 for group buy.
I just replicated layout from post #266
Tried hands on this layout. It is nicely done by DIYA member 'Project16'. :clapping:
Its aleady nice grounding layout post #266.
I just replicated it in software with some addition of 0.1uF shunt capacitors across PS filters. It has optional D1 (1N4148) and PS ground is separated with Analog ground.
Trimmer pad size doubled.
And it is okay for single sided PCB. That guy is genius.
Edit:
Forgot to mention PCB size. Its 50.80mm x 57.15mm.

Wishlist (culled from Jean Paul):
Stereo board
PS on same board (detachable)
Connectors for a potentiometer

Some WIP pictures:
Hole for IEC socket being cut away:
All done and singing:
Will relocate volume pot as it is too near PS board. Front panel on/off switch to be wired up. Have to figure out a good rotary source selection and wire up inputs 2 to 4.
I used a cheap steel cabinet but it is turning out to be much better than I expected. Size 12 inch wide, 8 inch deep, 3 inch height.

Ok l will try some low noise regulated PS with AC shunt after linear regulator. We discussed this in the past. Keith had suggested some circuits. I am not finding link now. But for this 10-12mA load we can do something special.
You could consider Select-5 Signal Selector Switch

theaudiocrafts has some source relay type selection modules, they are good for the price, but you can easily make it on a veroboard, even a passive selection rotary will be good for this application.
sann, this looks exactly like the one I have had in mind for a long time. Any idea if there is a local source?
For now I'm trying to avoid relay-based source selector. I have a kit and can assemble it but want to give passive rotary selector a try first. Thanks for the pointer.

I myself use a passive rotary based which i think is more than enough
Can you please post pictures of your rotary selector? Thanks in advance.

I will do that in a couple of days.
No, it can only be ordered from glassware yahoo store. I am currently using stereo to mono switch from them and the quality of the PCB and the switch is outstanding.
John Broskie is well known for the Aikido line stages.
Yes for sure most of the guys are again interested :lol:
