Not temp compensating components... temp compensating bias.

Oh...your bias is magical? It uses no components for compensation?

I always suspected your design to be that of an imaginary nature.

Not magical... it used the base-emitter voltage drop of an MJE3055T
(mounted directly to heat sink) to track with the 2SC2879 power
transistors. Since it used a transistor with gain... it worked so much
better than just a plain old diode on the sink for tracking. It worked
fantastic... I was able to set set class AB bias ( I chose about
200Ma) on the power transistors... and hold +/-5% collector current
changes from -40 to +100C heat sink temp during amp operation.

How well it works depends on how well you hacked the design from this
link I posted (while pointing out some of the many problems with your
earlier splatterbox):

That's interesting. Previously you said your bias scheme can "hold the
500mA bias to 10% from -30 to +85C". It's funny how many times you
have changed the specs. I especially enjoyed the time when you changed
the power output specs three times in one week after you were caught
fabricating them instead of actually measuring them. Oh well, such is
the life of an internet-educated hack.

But alas, there's still one unresolved issue here, Brian.... where's
the schematic?

Those who advocate high distortion levels and poor quality signals can spend

That's just what the average cber wants. Makes em think they got a

I never left, Brian.

I'm glad you're amused. But don't you think it's time for you to get a
job and relieve the financial burden on your parents and the Illinois
welfare system? If I lived in that state I would be outraged that you
are leeching my hard-earned tax dollars, but I don't. I guess people
over there prefer to coddle malingering basement-dwellers. You are
certainly lucky to live in a place with such generous folks, Brian.
Over here on the left coast you would have to support yourself with
gainful employment. And I hope that gives you something else to laugh
about, cause the thought of you actually working for your keep sure
leaves -me- ROTFLMMFAO!!!

BTW, where's that schematic?

This is the first time I've been to that link. The circuit he shows
with the two transistors is similar to mine. My feeling is that his is
needlessly more complex, but I'm sure it works. I also agree with his
statements about the diode method used for tracking. That method works
a little better than no tracking and is not worth the effort. This is
because putting two diodes in parallel never works right. One always
has a lower drop... and hogs.
