but I didn't order boards? -

has any of the pots been shipped yet? -
not worth the hassle ...

@UFN depends on the current setting and rails ....400V rails and 20mA will give you 16W for two 10m90 ...upping to 450V will give you 18W ... Load the PSU with 5-10k power resistors I have some cheapo EL34s for testing

any news in rgrds to the mafia DAC?
-
I guess not
-
are there any particular reason to building this amp? does it represent some kind of improvement in comparison to the other designs available?
-
that should get some severely extensive posts comming from the bikeshed, I'm sure
-
Mr. Retired-to-behinde-the-bikeshed is probably pointing to the design of the price tag itself rather

I was asking if you are planing on updating the TOGTE with available parts any time?
-
anything you plan on doing?
-
What happened to TOGTE btw?
-
The information posted by @mwl168 are accurate; I've used several of his Mouser BOM's as a really nice starting point.

Thanks to all for your very kind words about the build. The chassis is a standard Modushop Dissipante 2U/400mm. Customization also done by Modushop: Drilling/re-anodize the front plate and printing. @Pars: the re-anodizing seems to result in a more refined finish

AOIP (Audio over Ethernet) or is USB dead?
sorenb replied to astrostar59's topic in Home Source Components
done with what? -
you need 6V for drop, and you have 22.6V
-
just populate the middle bridge and you'd be good

two resistors in series, with some isolation ...the shortest distance bewteen the drains and feedback terminals...I did it on the backside

Feedback loop seems way too long - having it implemented at a separate board might not be the best of ideas.

Yep. diodes are protection for the opamp. Probably Kevin left those out since the servo input original was suppose to come from the output board via optos and thus not needed. the parallel resistors is there to raise the current but not needed here.

Seems ok. I'd kept feedback on the driver itself, and feed the servo from the driver board as well. As far as I remember 2x 1M from the SiCs of the driver combined into the OpAmp and the +input grounded.
