I have tried to put it in simplest technical wording possible. I hope it made sense.😀
No Thanksgiving day in Europe as far as I know, but hey, have a nice Thanksgiving in US & Canada.
Hi i have first version of low voltage salas it is a new better version of salas? Mayby something similar to hight voltage salas ver 2 with 2 mkp capacitors ob board?
It is realy better than ver 1.0? Can anybody give me a Eagle file , a will try to make my pcb. Thanks!
Do you know it will be only a board , or full testet power suply? What about shiping to poland?
Board. Few key parts options also. Read there in the gb section. People from all countries enlist and make an order for all from time to time.
Merry Christmas guys 🙂
I thought to finish my reflektors these hollidays and today I found that ampslab got these 2SK117 2SK117GR Toshiba - Buy Online @ AmpsLab back on stock. As for the 2nn4403 I want to use a substitute which I found also on amps.. site, talking about these http://ampslab.com/Freewares/2sa1317.pdf , are they better ?
As for the 2sk117`s I know they have to be gr,as for the 2n4403`s if I remember correctly their hfe must be ~200 or something more?
the hfe factor of the 2sa1317 I want to buy is T (200-400 says the datashhet )

One more vote for the reflektor Salas🙂
Used it to supply 5V to the excellent Subbu 9023 Dac from the GB here.
Used leds fro Vref, in order to have no drifts on the supply voltage, do not want to burn anything on the dac, as they are quite sensitive and really do not want to do any more SMD soldering for the time being!
Compared to an lm7805 regulator, the difference was huge. Bass was oveblown, sound was harsh and flat. With the reflektor, voices became natural, and sound had more detail, more depth and height. I didn' t expect such a difference.
Now waiting for a nice box to put everything inside.

Nice
Basically, 78XX should not be used in any of the audio circuit. Too much noise.
No, I did not order the PS GB, because I already had 2 reflektors assembled and tested, and with all the favorites comments about them especially on digital, wanted to use them. I did this test only to compare and see if I get much difference, considering there are another 3 reg on board, and I did get more than I expected.
I also built the reflector to power the Subbu V2.6 Dac (older version) for quite some time. Recently I built a second reflector just for experiment of changes in parts. For 5V output, one green + one red LED is the simplistic clean VERF 🙂One more vote for the reflektor Salas🙂

Better than the LM7805 is an under statement, to my ears, even the LM723 based PSU deigned for the Dac is not as good 🙂
BTW, after an extensive listening time with my p2p Bib and Reflector, I conclude that the Reflector is my choice.
Salas SSLV1.1 BIB board
Hi, I don't know if this is the relevant thread, but it is to do with working out the dummy load resistor for the back in black Salas SSLV1.1 BIB board. I want 28volts and 0.06amps so I worked out the resistor to be about 470R ohms?Have I used the right units.? Thanks Alan
