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

looks like 20 bit plus 7 segment supposed to be sign/magnitude but not sure of that

i will take a set of input boards please

2n5564 is the original part, however they are going to be very hard to find

for 15V, have to recalculate the values of the 1M resistors. So one of them would need to be 473k

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

kerry, any chance of a grhv supply that size

a neon test light works better

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

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
