An externally hosted image should be here but it was not working when we last tested it.

Compact in size, but not in sound 🙂
If you wonder where the Salas Shunt Reg PCB came from, it's Home Brew. After talking to Salas he graciously let me use the original artwork for the Mesmorise which I cut off the B1 portion. For some reason my H.B. DCB1 wasn't at all reliable, probably down to a track shorting somewhere. I eventually kept the PSU part and reverted back to my H.B. Pass B1 with the huge Obligattos. Result is pure Nirvana.

I've changed 10uf capacitors in my B1: ClarityCap ESA --> WIMA MKP4 250v. I can tell that they are quite good. Very neutral, very! They really sound good! They are cheap (can be found at $15 pair shipped) and fits perfectly, leading spacing exactly as on the PCB. So, if you do not to spend much on Audio caps -- these are highly recommended.
Thanks for the build process 6L6. I have a couple of questions thou
I have the same switch as rabaird, a 6-way 2-pole from HifiCollective.
As I understand it the B1 has 2 inputs. I need to use all 6 on the switch. Do I wire all the inputs to the switch and use only one of the B1 boards inputs to receive the 6 switched inputs?
Also is it possible to have get 2 outputs from the B1 by wiring to both the boards inputs? Would help with bi-amping
Many thanks

Yes.
I think you mean wiring to the outputs. Just run the output from the B1 pcb to 2 output jacks.
Yes, that PSU will be fine before the B1 PCB. There is enough filtering on the B1 PCB to use an unregulated supply, so a regulated one like the link you show will be much quieter! 🙂 🙂
Tnx 6L6. So I wire 2x pair of phono sockets for the output. Does it matter if I do that series or parallel?
Hi tinitus - does that mean double up some of the parts from the B1 circuit or a little set on the output jack terminals?
I was thinking I could run 2x pair of wires from the input selector and run both sections of the B1 at the same time giving me 2x identical outputs. I think I'd need to do something fancy with the volume wiring thou. Was that dumb?
I think he means to have a C x01, R x04 and R x05 on each output jack.
(Just to clarify, "C x01" means either C 101 or C201, the first digit is just the separator for the L or R channel)

6L6, what a great job on build and info, both. Is it possible for you shed any light at all on the chassis you used? I remember you said it came to you thru a friend. It really appeals to me, and I'd like to be a copycat!

I believe it was from a long-gone place called 'diy hifi enclosures' or something like that...
I'm sure there is something similar available, but the exact one? Probably not. 🙁

Hi,
Would it make too much of a difference if i used the following capacitor for C101 and C 201 instead of the 10uF as mentioned in the B1 buffer article.
AXON-73703 11uF / 250VDC, True Cap,* 22mmD x* 38mmL
Thanks
