lol i tried mate. i guess you'll be going through it after all

@ jtktam : you read it, its not interactive. first 2 rows are input stage voltage and fet voltage, then various bias settings and on the right power into 8, 6, 4, 2ohms for those 2 voltages

Wow... that didn't take too long!

Alright, I'll bump the PCB limit to 100 by adding another one to the panel. I would really like to see 50 kits in order to get good pricing, so if it comes close, preference will be given to those who ordered kits.

I'll field the technical questions this evening.

Regards,
Owen

Hi is it possible to have the boards shipped to england and if so what sort of price we looking at?

Are there any more performance characteristics? THD vs. output power?

Does the LME and the FETs have to be at different supply voltages?

Thanks
Boscoe

no they dont have to be at different voltages, but you get better performance if they are. you can feed them both from the one unregulated supply if you like, thats how it was set up for the measurements, so you can expect even better if you supply the front end with a higher preferably regulated supply. all of this is covered in the first post.

good form pchw!!

yeah that was insanely quick, like less than 24hrs haha i would get kits, but i already have quite a lot of the parts, not least the lme

i'm going to be running these on mf30-1f-75 conrad sinks,which should be good for >150wpc with passive cooling, thinking i might up that with a couple small fans. if anyone else would like to get these let me know, perhaps we can get a discount.

anyone else interested?

we should gb the tx from antek too, havent got time for that too and it would be more logical if someone from that side of the world handled that.
