Current source for BOZ

harvardian · 2nd May 2002, 02:33 AM

Would there be any sonic merit in providing a current source for the BOZ design? Any ideas?

Thanks

Dale

1.Yes

2.Yes

Ok Harry,

Could I use an Aleph like current source or should I just try a DC one? Any suggested values/circuits?

Thanks,

Dale

P.S. I do enjoy your humor... except when I want your knowledge.

Dale.

You might have to bribe Harry with a case of Foster's larger.
Harry is correct but if I were you I would build the balanced version and current source that.

The reason that I ask is that I just traded HPotter some transformers for his BOZ with transformer and pot. I know that the Balanced might be better, but this will be easier.

P.S. Harry, where do I send the beer?

Jam,
Would it be better then to built Aleph P1.7?

AudioFreak · 2nd May 2002, 09:57 AM

given that it is such a low dissipation i would use a standard dc current source.

Peter,

I think the Aleph P 1.7 is a better preamp, it seems to be more datailed. I used to own one but if you like a slightly warmer sound stick with the balanced Zen. However both are excellent units.

So finally somebody shed some light on how those two preamps compare. I think there is another advantage to Aleph P. It uses only positive supply while Balanced BOZ needs both positive and negative rail.

Jam or anybody .......
1. Is building Aleph P 1.7 a lot more involved than building BOSOZ?
2. If it is, what are some of the tricky areas?
3. Isn't it true that they have a patented volume control?
4. Is the volume (controller?) easily built too?
5. Does anybody know approximately what it would cost to built this pre-amp?
6. Is all the parts shown on the schematics easily obtainable?
