when sales of tle ll2t drop to zero. but he is still going to have to do a major redesign to get that to happen

you pull the opamps, and start with all the pots in the center. the pot in the middle of the board, you adjust so that the outputs are centered around zero. Then you adjust each other pot to bring that output to zero. then you put the opamps back in.

now where have I heard that one before?

gfi outlets will not work without a real ground. they work by measuring differential current.

that depends on whether the output is true balanced or ground referenced. true balanced may cause interesting dc level issues releated to common mode.

should work from +/-400 to +/-550

if your water pipes are copper, they are usable as a ground.

reduce the gain of the amplifier by lowering the feedback resistors

for a 10k pot, the series resistors should be 10k, and then calculate the other resistor for the attenuation you need

buy the neutrik xlr-male to xlr-female adapters and pick your attenuation and use either 3 or 4 resistors depending on whether the dac is really balanced or not. http://www.mouser.com/ProductDetail/Neutrik/NA3FM/?qs=sGAEpiMZZMv0W4pxf2HiV9y0EyfHsAgRI%2fcUCPoRaKI%3d

Which is insanely high, but lots of dac's are doing that these days. You need a 10db balanced pad on the input.

icarium has one of my cases

yep that is the one.

suggest you buy the transistor tester meter on ebay, cheap and the best way to test them before you stuff them in the boards and then find out they are not real.

those are vertical mount resistors to keep the board size down

actually use a 12V car battery. you will find the shorts very quickly

i have a few left

typically you cannot get it to zero on both sides. But if you can, it should be stable

not only is that plug a piece of shit, its the wrong dimensions and will crack a real stax female socket.

singlepower would have used super glue. just like he did on all of those blackgate caps

i went back to the pictures to make sure all of the parts on heatsinks in the original are on the common heatsink bar in the diy-T2 there are 2sc3675's with no heatsinks in the original, and they are that way on the diy-T2

So i can certainly make some of those, and out of the metal that turns superconducting at LN2 temperatures. Put over a rare earth magnet, and they will spin for a very long time.

you do realize that giving me idea's like this is only going to cause trouble

very sweet now you need a 2 color power switch warming is one color, on is a different color (from joamat's T2 boards)
