Re: Re: preamp
Absolutely, mine has 8 outputs, have used 4 at a time no problem, take a look at my BOSOZ (not the X version....yet)

Now to the question; Is the x-bosoz capable of driving 2 balanced preouts?

Re: Re: Re: Re: Re: preamp
Do you think it'll sound better?
If built with good components and wellbuilt, in what price range among commercial products can it compete?
I'm not counting building as a cost, since I love doing it.
Now I've got a few more components to buy, of which one is a pain in the A*S! In sweden you can't buy the LM4040-10 unless you order as a company..... so if any of you has 4 of them to spare.... I'd be grateful.
Of course I'd pay for them and the shipping costs.

I hope so, I took about 2 years building the original version and during that time the X circuit was developed so I kind of feel that I missed out on it. But I did it for the learning and the fun, so am not too concerned. Yes, this is as good as commercial preamps.

Just FYI, I'm working on the main boards and have discovered that the 100V, 1000uF capacitors in the layout have holes that are too small and spacing which is too narrow for the snap ins that are specified by Nelson for the BOSOZ. In fact, I'm not sure if any caps of that rating will fit in there. Just FYI, I drilled holes to put the standard caps in there and it affects placement of the nearby resistors which are overlapped by the large capacitors.
I would not call this an error as its possible that there are caps available somewhere that will fit. Just frustrating that the standard ones dont. Hey its diy so we all adjust.
parts
Yeah this GB went bad from like every perspective. I thought there might be a problem when I read this on the wiki:
I really feel bad for all of you with no boards and parts, felt bad for myself waiting for months for the ones that actually showed up.
For those of you who have given up on parts, check out this transformer.
The one transformer should be sufficient for a dual mono supply, two 55V secondaries and two 16V secondaries, one for each board, no? And a bonus 14V secondary for all your blue lights.
Hmmm.... are the 16VAC secondaries too high for the negative supply?
....best part its only $30.

If it helps, it doesn't have to be an LM4040-10. Any decent voltage reference in the 9-12V range will be fine. If push comes to shove, a simple zener diode can be used as a replacement as well.
I have been eager to answer that very question with mine, but have had limited success finding people who are willing to do a comparison against their gear. The only preamp I've had a chance to compare against was a Mark Levinson 380 preamp, and my CC-CCS-X-BZLS held its own. I liked mine better, my buddy liked his better, but we both agreed that they were in the same performance league.
Just don't think of scrimping on the power supply. I'd take Nelson's BZLS PS as a minimum requirement. In mine I put a CRC filter before the regulation stage, and added more capacitance after the regulation as well.
