Hi, all. new here.
My electronics background is pretty spotty. Please go easy. I'm pretty good with robotics, though.
I just recently gutted some not-so-old-but-totally-fried Sony and Kenwood amps. The power stages and related circuits are good, the controls and preamp (on one) are fried.
I want to try my hand at building a stereo power amp, preferably a class AB or A.
I have a choice of either these MN2488 and MP1620 Darlington pairs from the Sony or these 2SC2921 from the Kenwood. Which would be better? Also, how would I measure the transformers (LOTS of secondary leads) to find out which voltage is where? I plan to use the original caps, etc. all on a new PCB, of course.
Any suggestions for a beginner prject, or is all of this "recycling" not such a good idea. Aslo, I'm poor and doing this on the cheap.
Thanks in advance....
