At some point or another, we have all lusted after people's gear signatures. However, whose music collection would you like to have?
For me, probably Deepak. I'm not sure why, but with some of the things he's sold, I wonder what he's keeping
interesting. However, I'd take two very stable separate supplies, to an unstable tracking supply any day The HP looks to be a good choice in fact, assuming it is or can be brought up to the claimed specs.
must it be dual tracking? I'm not sure those exist.
I have a pair of the ones mpwi linked to above, and plan on using them to troubleshoot a beta22 board or two really soon. Obviously, I won't be able to dial in the boards, as I'd need the final supply for that (due to the fact that you sorta get what voltage you get with the sigma22) but you can put them in current limiting mode and fire up a iffy board or two with them...
I'm trying to envision a "dual" supply that wouldn't work (i.e. these "mixed reports"), perhaps you have a link?
I'd rather have one that uses the dual packages... or at least, the singles closer together and somehow thermally coupled. I'm not sure which (if any) of Justin's use the singles, so I'm sure this statement is of little help..
actually, it was quite hard to find 26 awg @ 19/38, but this stuff looks nice. (note the other 26 awg is 7/??)
Still trying to find exactly the right formula red fingernail polish though
