No, its Oliver's PCB V1 they used for an AD filter-less dac with SRPP I/V.

If you mount the FETs to chassis, and have electrolyts for C (for clocks), you can make the pcb real small

HI,
Thanks for the complements and the advise,Yes a little ripple way up but very acceptable ,I will see if it can be eliminated,I didn't need the relays so Thats why I constructed the Mez,It works good ,I have nelsons B1's also and compared them,In my ear at the same volume level they are the same,Both Excelent,The shunt is prettier all those lights,Might go in a Clear top case,lol.
Is the circuitry for the newer designs better? Sound better?,lol.Maybe I should build one and see,
I see those boards are in the store ,might have to get one,,,,,,,,
Thanks Alot,
NS

Most reports claim they can distinguish the DCB1 from B1, only the lack of 2 coupling caps should be a change. The Mez board on the store gives you full switching capabilities but has no core audio circuit differences to what you put together.

hello Salas ,

I want to build a final version of my dual mono pcm1794 dac and I was wondering which version of all do you reccomend for 3.3V and 5V?
now I use V1 and 3 x 53Ah LiPo cells to power the little pcm`s.should I change to one of the newer versions?
thanks

There is the 1.1 bib soon on new gb round that you can use in Mosfet for the 5V and I would recommend the low vgs ST output Mosfet p2p version of the Reflektor for lower Volts as discussed some pages before and made in Japan.

from what bib comes?
in my 3.3V shunt I use bd140 if I remember correctly
didn`t manage to find that discussion

AAHH Good ,
Thanks for that info on the B1-DCB-1,circuits are very similar,
I fiddled with the scope probe and it did indeed move the wave form ,so it is correct that my measurement is not totally accurate,my meter also influences the signal,It sounds good and I am HAPPY with it performance , Thanks again,SALAS.
Happy Listening!

BIB means back in black for returning to black solder mask-gold pads boards GBs color scheme. Its the SSLV1.1

As for the 3.3V Reflektor you could not find, here it is The simplistic Salas low voltage shunt regulator & The simplistic Salas low voltage shunt regulator
