Thank you for this explanation. I’ll bookmark it. We have come a long way since the 4 diodes in a bridge plus capacitor.
And that was already radio-2.0 for me. Because my first kit radio had a triode… on batteries! What a disappointment. Many years later I found out that my father believed he had found a trusted source of almost-good-as-new zinc-catbon batteries.
uh…wow this is amazing.
Thanks for the write up HKJ and taking the effort to educate us all, some more than others I guess. :+1:
good job.
btw the sanyo 3300@10 is a fake.
something you will often see in this class of stuff.
all too familiar with the rfi issues mentioned by sp5it.
seems the easiest place to cut costs is the elimination of rfi/emi parts followed by output caps.
the first makes the unit noisy junk .
the second causes its early demise due to output caps blowing up.
