Default Stuart and Neil Build a KSA 50 (tweaked for 100 watts)

It has been a solid year in the making and the final results are well... let's just say that we are very, very happy.
There will be more information to come, hopefully a web page documenting the trials and tribulations of this crazy actively cooled Class A 100 watt monoblock amplifier project. But in the interim here are a couple of teaser pics.
In the end we hope to publish the how too manual for anyone crazy enough to take on this project, from sourcing the chassis, hand winding the toroids, fabricating the cooling tunnels and wiring these beasts.
Thanks for looking and check back for updates and URL links

Way cool!
Look forward to updates esp. images and details of cooling. No fans I hope right.

Thanks for the info! These appear to be awesome "little" amps. These are the same that we saw and heard at BAF '08 last week right?

If so, they look and sound great. I was very curious to see a little more detail.

I likely won't be building any Krell clones myself, but wouldn't mind borrowing some of your chassis ideas!
