Long way to go and not going to finish before it gets packed up but plan is to have all the electronics installed within the enclosure even if not fully wired.

Cool. Here it will be about 20cm or so. It's not fully wired up but this is about as far as I'm going to get this side of the Atlantic. I just hope I can remember how to finish it when I finally get the chance to start again. :eek:

Here's the duo (or should I say trio of channels)! :D

That looks pretty good! I know that it's hard to get those low distortion readings with the PC soundcard method. You get the cabling never really hum free.
What me wonders is that my ARTA version is able to print the IMD values in percent on bottom of the IMD pictures. Whats your ARTA version? Or is this the free edition?

All test using esi julia pci sound card.

Looks like you are testing your soundcard in loop mode...
Time to put the SA2015 power amplifiers in a case
Exactly!
All measurements are close enough to sound card limits.;)
It's my wish but i can't afford the cost of a case (about 220euro)plus the cost of a proper power supply(100+euro) .:(

Dave Zan's simulation models seems to match pretty good with the devices in reality. Bias settings in reality as expected from spice design!

Hi Dave Zan. Could you please put up for download the spice models you created? Save the rest of us having to create our own models from scratch. TIA.

(Not impressed by the fact that IXYS still haven't provided models for these. )
