25 watts per channel pure class A is just barely enough to run headphones but more than enough to run a pair of klipshorns (to ear shattering levels)

machine on different subnet now, all should be fine.

ok, the thing before the craptor then.

birgir needs to post public pictures of his new house. I would kill for a view like that. (and free heat)

Hawaii, north of vegas, something like that. had enough of illinois budget woes, as in not plowing the streets in the winter more than every other day. The trick is making a 24 bit dac that actually meets the specs that some people out there quote. The rest is pretty easy. And the data i/o is heading to the recycler today. found a fool to take the metler as an antique show piece.

not that long

this is going to take quite a while!

and this is why I try to design for the lowest dropout voltage possible. Especially true on the high voltage supplies. But still you have to have enough to work with at least 5% low line voltage. so you need a different transformer.

not a good idea to do that to the diaphram

so with any fully dc coupled circuit, if you put a balanced signal on both inputs say -1 volt, the output of both drivers will go to -VCC (400,450...) resulting in a dc bias on the headphones of 1kv early srm717's had a protect circuit for this, but it did not work as the relays ended up arcing thru.

Current output. Even a short to ground won't damage the amp, but will throw the servo off.

I hate it when that happens. fixed

i think i have a bare board, will look later

it better say 2k on both sides, but it might look like 5k flipped yet it sets the gain

so i'm not sure that is what you want because then the minus supply is completely unregulated which is the problem when you try to split the ground with only one regulated power supply. in effect it shorts out the 2 x 365k resistors. http://gilmore.chem.northwestern.edu/srxshunt3.zip has a position to short the unreg ground and regulated ground.

you don't want the tube sockets all the way in otherwise they are too low for the chassis.

pretty sure the goldenreference.pdf is the latest version

so I wire mine for balanced input only, all 4 wires go to the pot, and then when I need unbalanced I use unbalanced to balanced adapters which short rca ground to ground and xlr -

updated volumecontroller.zip http://gilmore.chem.northwestern.edu/volumecontroller.zip

sure seems to be very similar to thunderbirds...

power supply makes a big difference

don't see any ac25 in that picture depending on which supply, some are dual 25v windings, some are 25v center tapped

finishing a project with a kintex-7 now so yeah whatever one has more than enough horsepower and compatible with the xilinx compiler. the totaldac uses 74hc574, so yeah not so good either. if someone with the fpga tools wants to do that part, fine by me. I definitely want a dsd to 192/24 thing inside.
