Newbie question.

Does this mean that you can take some `nice' semiconductor and cascode it with a monster hockey puck: some super delicate jfet/SIT/vfet and hang a great big high gain switching lump on the side and get all the nice character of the `audiophile' device with much bigger output?

Hello,
It has been a couple of years since I have been on here due to operations and Hospital stuff, I was wondering if the following website is still reliable
http://www.kk-pcb.com
for ordering circuit boards for Aleph amps and power supplies, I haven't decided what to build. I might do a set of powered speaker like the ones Nelson did a while back with multiple Aleph amps inside. I prefer active crossovers and sealed cabinets with DSP for bass extension. I can't find any current comments on the reliability and quality of the circuit boards and stuffing lists that come with them on this site. Anyone know anything?
Thanks,
Brian Burke

You would do best by first looking at the diyAudio Store to see what is now available in legitimate PCB's.

Amongst the many items you will find a universal power supply board suitable for any First Watt amp.
