Hello All!
This is my very first post in this forum
I've been watching for a long time the amplifier topic in this forum, but still haven´t taken my knowledge - my English is also quite bad Anyway I posted a picture in my amplifier experiments of Apex SR200. It has not been tested yet, heatsink must be machined, as well as the electrolytic caps solder for place, then I will test the amplifier.
