DC-protection for my ZAH3 amp..

[nikwal]

So i made this Dc protecion device for my zah3(as i call it) amp. Ok there are a lot of them on the net but i did not find one I liked very much.. hmmm but I come to think of it now, I didnt make a slow start, do I need that maybe? well I'll find out later..

hmm

( the zah3 prototype, hmm hmm over the years I learned that this configuration of the BJT transistors is a must for me, first saw it on maybe yamaha A1 or something like that later learned why it's needed to put two transistors (for example) in series like that)

I always make very good looking prototypes ;-) ;-)
