I don't suppose you have a schematic of that available on the web. It would
be neat to see.

Well, I am looking at the picture.... We i nEurope use metal film resistors
now almost exclusively I think, not carbon? Maybe it is just the color coding.
It is quite easy to make a partlist from the photo, many things are obvious if
you look up 2SC2829 application notes....
I would expect some thermistor for temp compensation, he is so proud of,
do not see it.

I just did some googling,. yes I like FETS,

But for his first amp ;-), not bad!


It's not his first amp..... more like his fifth or sixth. He's been
using this forum to spam his junk for years. Go back through the
archives and you will see discussions about the cheap, diode-biased,
class-C hacks he has tried to pass off as a "linear" amps. He even
went so far to defend the designs by saying that "Linearity is not
'required' for AM...."; invoking the flywheel effect when there was no
flywheel (tank) in the design; declaring that a 179 degree conduction
angle did not introduce any significant distortion, irrespective of
the low input impedance of the transistors pushing the conduction
angle closer to 120-150 degrees..... and a bunch of other technical
voodoo, hocus-pocus and nonsense. And all the time claiming to be a
professional engineer while dismissing (yet later incorporating) most
any constructive criticism.

The only thing the Professor has professed here is fraud.
