The Multi Amp aka Dynalo Mk2
because then you still need 2 of them and then a dual xlr to single 4 pin adapter Mikhail did this stupid shit on that monster I have.

CLOSED - SR-X Plus and JimL Shunt Regulator PSU Boards Group Buy
new amp board srx6rev2 with all of the latest additions can use -20v supply, or add resistor and zener and run off the -340v supply board is exactly the same size with all the mounting holes in the same places, 8 more holes added, should not influence the price

What Are You Building Today
are you leaving the transistors on the mini boards, or are going to unsolder and use later.

The Multi Amp aka Dynalo Mk2
that gets expensive, but sure.

4 pin, ABSOLUTELY NOT you put a 5 pin on the amplifier output. and then a 5 pin to 4 pin tail for balanced, and a 5 pin to 3 pin for se.

goldenreference low voltage power supply
its fine for digital, just seems a bit of overkill when a standard 3 terminal regulator is enough. definitely change d4 to 5.1v 4.7v is too low and it will not start.

goldenreference low voltage power supply
never tried it that way. a little over the top to use this to power digital. does look like it will work.

I shorted out the power transformer while recasing my dynahi. Help
actually if its that old, your electrolytics are starting to die...

The ultimate DIY? A Stax SRM-T2!
i soldered the filament wires directly to the jacks.

and now for something completely different part 3
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)

stax mafia circuit boards see updated links on page 5
machine on different subnet now, all should be fine.

ok, the thing before the craptor then.

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

Stax mafia multibit dac?
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

Stax mafia multibit dac?
this is going to take quite a while!

goldenreference low voltage power supply
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.

Blue Hawaii Special Edition
not a good idea to do that to the diaphram
-
Blue Hawaii Special Edition
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.

transconductance amp
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
