GB for DC coupled B1 buffer with shunt PSUs

[tinitus]

I hate to say, but this begins to look messy

Please, we need to find a way to get control of this

Yes, please. I did not want to derail the fine work going on here, but somewhere after Post #142 when we said we were good to go something happened and now we have relays and powersupplies for relays, etc. This is all well and good, but I still vote for what we originally started out with and would like that to happen, here or in another GB.
It looks to be an informal 3 people so far with this thought.

Yes,but the problem was that I only had the pdf file.So sommeone had to redo it in a layoutprog,and that was done in post 153
and if those files are for us to use,I don´t know?

hi guys.. i'm with the group decision.... sorry if i took too many request.. just make the final decision so we can move forward..

How about make it 4 :-)

Personaly I don´t need the relays.but I am going to build at last one buffer,and use the others for only PSU.So I guess I´m in on the one without relays.

But if we get a 50-50 situation we could do 2 GB..

Are we going for the original single sided board, or the one in post 153?
Either way is fine with me

The version with double bridge is nice, though I would still suggest to make common ground after supply caps, because of ground connections to other active parts, but just a minor detail

A more advanced full blown board should be done in a new GB, and Im with that one too, when it happens
Maybe with LDR attenuator

I like the possibility of using heatsinks.

Yes,maybee you are right there.. or who knows where it will end..

Please forget about the double bridge and read the posts why it is not OK to use 2. This was explained at least twice.

OK, if anyone wants something different things will start to look messy as the requests won't stop and they 'll all be different or even contradictionary. Nevertheless the board got better and better so till now things only have moved forward.

What is the project ? A design of the PCB for a symmetrical version of B1 as designed by Salas based on Pass labs B1 enhanced with a shunt power supply. It is NOT a stand alone power supply for other purposes but it can be used that way. If you want so you are on your own. This thread is about a buffer with its own power supply.

Who is in control of decisions ? IMO the designer is leading. To avoid further confusion some of us will have to make decisions and the designer must be willing to carry out the work. It seems xaudiox wants to do the full job for us which leaves the question who decides what the design will be. Voting is OK but it will take time. If the design should cater for anyones wishes we won't ever see it finished I guess. Democracy has disadvantages too.

The advantage of a full fledged PCB ( or separated into 1 PCB with the supply and 1 with the buffer as proposed by xaudiox ) is that you can simply omit what you don't need. So it will be enough for all whereas a simple version will need extra circuitry which means more work for those that wanted a full version. A simple version needs extra PCB's and wiring for standard functionality so why not go for a complete design ? Board space is not that expensive anyway. Just my 2 cents.

So let's make a decision. Who wants a complete solution where the extra's simply can be omitted and who does not ? As you can see I am positive about a full solution but I would agree with the simple version if the majority would like that.

Do you mean the pcb in 3 parts?One with the PSU one with the buffer and one with the relays?Would that be possible?
So all is satisfied..maybe the price doesn´t have to much higher.
