got them, the connectors are pieces of crap, one side is intermittent if you shake your head hard, but sound wise pretty comparable to my lcd2
may actually be built a bit better
the pair of 1.5k resistors and the 10 volt reference make a 20V output voltage
the pair of 1M resistors and the 100k pot are for trimming the output voltage and are optional
not sure where the 750 ohm came from
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.
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
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
