After my Aleph 5's - project I got my hands on some vintage JBL drivers. I was planning to drive them passive with Alephs but I couldn't find original xo's anywhere. So, chose to go active then.

Lurking around internet couple of nights and trying to find suitable low power class-A amp to drive JBL horns. Soon it was clear: Amp camp amp. It's proven to be good quality and nice sounding piece of amplifier.

I ordered pcb's, Trafox toroid and rest of parts I had already. Case is home made again, tried to clone some of looks from my Alephs, mainly for the top/roof part, but this is not the easiest part without proper tools and workspace. Light inside indicates power on.


Single-ended class-A.

Trafox 160VA 2x18v toroid.

44 000uF filtering per channel, 88 000uF total, basic CRC supply.

2 x 5w@8ohm

Sinks are from old broken Nad 216.

Thank you Mr. Pass, thanks DIY-community. Thanks Pia for welding trafos L-stand.
