A Resistor capable of withstanding more current briefly. A more bold and faster transistor in comparison to the tiny 1-watt BC-thing As I have stated on page 3, powering up the driver and let it settles before dialing in the output bridge will bring the Albatross up in the Air; landing is likewise a bit delicate, and turning off the HV900's before the drivers works. I suspect that the 120ohm's also needs to be of a more bold character to prevent this thing for going boom - maybe 100W bolded to the heatsink.

you can tap it off the drains of the SiC's at the driver board using some resistors. 20V offset will whack the bridge out of balance and raise the current flowing. The zeners at the gates provides some protection in that regard, but I suspect that those are slower in comparison to the SiC's and that is the culprit. I suspect the HV900 current limiter isn't robust enough for being literally 'shorted' for a very brief moment when the driver at power up/down swing to B+

didn't you use lm49830 for the blackhole buffer?

how does this compare to the 49830? (I know it's obsolete, but still)

delivery to me week 06, will ship immediately hereafter.

Haven't tried the software Congo5 points to; I use the free GerberLogix that directly supports zip'ed gerbers (even drag-n-drop). Haven't tried all gerbers from Kevin, but a fair amount, and it seems to work fine.

U can go Bax with Stax: Tintagel sounds good and, even the sick Tristan is quoted herein

Received in good shape - nicely packed. Thanks for all your efforts doing this, highly appreciated. /S

Perfectly fine. I was worried that the package had been sent and gone missing, thats all.

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
