First position in the chain is the transformers, which is then connected to the new PSU (AC/DC), this is then connected to the Salas Shunt Regulators which produce the 24vdc, which is then connected to the 2 pcs main board (which I call motherboard) which houses the gain cards.
So I guess what I am asking is, can one use standalone transformers and skip using the previous or original PSU card ?
Answer is yes. This new main power supply PCB was made as a replacement option to the old one.
By the way its PCB dimensions are 150x150mm.
Excellent. Thanks for the work Eric06. I will probably use this one rather than the class-A Smooth as butter 🙂 - so count me in.
Hi,
since nobody answered your question, then I will.
Answer: Yes you can. But the rotary switch have to be a "brake before make".
Can be connected with wires here:
So you can proceed with your renderings 🙂

I think you will need a seven position ? Position one = nothing selected.
Not sure about that, so I let Alex or Eric answer that one. But, it has to be a "brake before make" switch.
If a 6 position is O.K, an Elma switch is a good choice.

If a rotary switch is selected instead of the pushbutton-switches, it would save people a lot of time designing/making their frontpanels.
I know……. 😉 Spent a lot of time designing mine 😎

Dear all,
In order to perfectly match the transformer, filtering, ... needs for the Salas shunt PSU, Eric quickly designed a nice additional external PSU PCB fully compatible (in term of connectivity - the DB15 connector) with the existing external PSU.
Very nice from him🙂
This can be added on top of the existing PCB list. Interested?
Hi Alex,
I would also be interested. And as Enrico mentioned in a previous post, if possible I would also like 1 or 2 extras of the board to substitute in a current UGS.
And thank you Eric for making it available to us!
Paul
also interested in the additional ups pcb‘s. also interested for 1-2 extra for current preamp wirh old ups...
