Tangent Poweramp - Lupus Servus
Here are some photos of the amp. Fall in love with all the heatsink. These must have been produced in a very limited run but I'm not sure how many were actually made. The serial number on this one is "0078".
As I recall, Tangent did not publish any specifications on the power output of this amp. I believe it is in the neighbourhood of 100 watts per side and it's always been plenty loud enough for me.
The front pilot light also functions as the on/off switch. Just push it in to turn the unit on or off. I've replaced the bulb a number of times but this is the last one I've got.
I'll try to get more information on the circuit design for this amp.
