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

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.

actually i have a surgical microscope i use at work. problem is its old enough that it has no center tube for the camera

That is what I use. but planning on a microscope with a had video camera not sure how well that is going to work

NO!

it would be insane to use this supply to power a laptop. much cheaper to buy a power-one for the right voltage and size a number of companies now making linear power supplies to run desktop computers. they are gigantic. And with the latest 6 and 7th generation intel cpus with the 12V only supplies that are rated at 20 amps or more, also silly to do linear. no plans on crossovers. I certainly know how to do them, but lots and lots and lots of parts

Any reason why you need more current than that?

lower the values of the 1300 ohm resistors

so I did something like that with an opa1632, everyone over at amb's picked on me, and in fact it sounded like shit. Then Ti released exactly the same thing. Still sounds like shit. Lots and lots of feedback is why. This discrete thing is pure class A and current sources, and no feedback. except for dc servo sounds so much better congo5 is testing the surface mount stuff, currently the output buffer blows up due to power over 15v, so will trim the current a bit, the surface mount transistors can only take 150mw. size vs power. It will run just fine on 15v anyway

yes that is how it works

sure as long as you don't mind the gain, or have a knob elsewhere (or a dac with a volume control etc)
