UGS MUSES Scion Preamplifier

[redjr]

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 ?

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 !
