UGS MUSES Scion Preamplifier

OK. Thanks for the clarification and LS part #s. I've been going over the BoM this afternoon. What tranny will use use for the 5V relays? Is that the right voltage or is it 9v or 12v?

It is a big project, but should be fun to complete, hopefully with few headaches. 🙂

Most use 24v that I am aware of. Check BOM 🙂
I will use Hammond 229 series, their 48VA, 28V (229D56).

Hi,
For the digital section you will need a 2x8V or a 2x9V AC (2x9VA) tranny.
2 x 24 V is for the analoge section.

That is correct, also market on the new power supply.

I believe the 229B56 12VA 28V should be enough....

 

[Oneminde]

The VA size can always be debated but it was recommended by a good friend of mine and he is using a similar size in his preamp.. so, why not 🙂

Hi,
That Hammond will need it's own pcb, since it meant for pcb mount. But sure, you are aware of that 😉 ? Much easier to use a toroidal or C-core meant for chassies mounting.

I am aware of the construction. Is or was considering an enclosure and potting it (which would allow for a conventional mounting) 🙂 .. well see what happens I guess. First need my boards and it feels like they are stuck in limbo, no shipping update since the 28/7 ..

I just finish and tested this new board with a 2X20V , 12Va 229B40 Hammond, will use it for the new UGC muse preamp with 2X28V, 12Va 229B56 Hammond.
that is an adapted Salas UltraBib with on/off.

Looks nice 🙂 - so you didn't order the custom power supply on offer ?

 

[Hicoco]

yes i did and i am not sure if i will use it, i prefer this combo with transformer and also i can connect to it other boards

 

[Oneminde]

Understood. Options are good to have and which ever solution is best according to you, is the one you should use. I currently don't have other options/choices than what is in the kit. Should be fine.. we can hope.

Hi,
The Hammond transformers are really good. I am using them myself. I was only pointing out that they need their own pcb. Here is three of them for my upcoming project.

 

[Oneminde]

To be honest I never checked if PCB's are available. Might design and produce in house if PCB's aren't available or do the shielding and potting... so many choices 🙂

What you working on this time ?

 

[Ine]

😉This one

 

[Oneminde]

aah... THAT one... he he. Yep yep, I have it on my list (purchase) in a few months.

 

[Ine]

Sure you are 🙄 Really ?

 

[Oneminde]

Re imagined 🙂

 

[Oneminde]

Have the "Danish" class AB secured, considering a very special class A and the there is the phono stage, besides the preamp ... that's where I am atm

 

[Ine]

Just dreams IMHO
I don't think you have the funds to complete such projectets, but suprice me !
Why have you not built the "Danish" class AB yet ? You had the pcb's for some time now ? Stop being such a "wanna be "
Let's see some progress !
