I don't believe that Mikhail ever sold it. At the time he said it was about $6k to gold plate it. And I don't believe that, probably more like $1k. He did try and sell it a couple of times for $35k or so I was told.

the board is the dual servo one, I thought I published the final schematic, will have to look
-
That schematic does not match the current board
-
yep those 2 caps go from +vcc to -vcc not sure why
-
as far as I know you have to gold plate the turd. then you can polish the shit out of it.
-
those have not been updated in a while, so many versions, sorenb probably knows more about which is which than i do at this point
-
is it anything like the final countdown?
-
found an error with the input board, fixed and updated
-
2x is just fine for this
-
i'm sure they can make a high quality amp. But they are subject to the same parts i use unless they find piles of obsolete parts. Kind of doubt they would do that at this point
-
maybe it will look like this. makes the rsa stuff look ok.
-
i'm looking at my board which is labeled 2009 Jacob potter and all the electrolytics go from power rails to ground
-
Its there now, I put it in the wrong place

Continuation of R2R DAC Discussion From Stax Thread
kevin gilmore replied to Sechtdamon's topic in Home Source Components
so if I count right, that is 50 resistors per string. which would work out to 25 resistors (sign + 24 bit magnitude) x 2 and then 2 of them which would be balanced for one channel. so it actually could be really balanced. 3 opamps at the outputs? funny that they sanded off the part number of the eprom that loads the altera chip -
Way old will have to look at it. If it has the 4pdt relays, those are obsolete board file posted, everyting is the dpdt relays. So you stack 2 for stereo, and use rca to xlr adapters for the unbalanced inputs otherwise it gets stupid complicated

the pile of caps could still be a pain but not for a while can't tell whether its sign/magnitude or not. if it is sign/magnitude, then its not true balanced -
Best news ever yamas sucks
-
I like those
-
I was thinking that you would not need heatsinks. Kind of expensive to use 3 in series might be easier to use 2 of the smaller ones in parallel depending on available values i had to use 2 in series for the esx

RIP Al Jarreau only got to see him once, completely unique
-
they are wirewound, not sure how much inductance that is going to add, or whether its going to cause any trouble. I would probably use these http://www.vishay.com/docs/50051/lto100.pdf
-
I doubt those resistors are rated for voltage, so don't mount them to the chassis, or try and find a voltage rating measure the high voltage transformer for leakage between the windings for the 900V

i use the stripmaster. does teflon just fine. justin has managed to go thru a few sets of dies, mine are still original 30+ years later, although i recently bought a new one as the handles on the old one are falling apart. -

definitely blame me. its my fault. its always my fault. This is definitely the year of r2r and the start of the end for megabuck stupidity. -
i have a nikon microscope that is setup that way. For some reason i have a hard time using it due to diameter restricted optics. And i'm not going to spend $35k for it.
