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...

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):

http://www.ifwtech.co.uk/g3sek/tr-bias/tr-bias1.htm

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.

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?

Glad you're back Frank... your always good for a laugh.

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.

Personally, I run a speech compressor. I doubt many of these idiots
could install one; apparently, they can't afford to have the local "cb
tweak" install if for them either.

Local, I kill the speech compressor, it is only for DX. Frankly, it
doesn't hurt my feelings they don't have one! evil grin

Keep up the sales pitch--few will be disappointed if they purchase one ...

Well, that is certainly better than a "Big-Headed-Amateur-Wannabe!"

Get mental help, the opportunity is still open to 'ya!

John... good to hear from someone who has some experience with
processors.
I'm curious about the one you have. Can you tell me about it?

Yeah, bull****. I've posted it four times over the years, and I'm sure
you've run across it in your quest for hackable designs.


The circuit he shows
with the two transistors is similar to mine.


Gee, what a suprise.


My feeling is that his is
needlessly more complex, but I'm sure it works.


Let's see -your- design, Brian.


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.


Yet you used it in your previous amps. You even defended the design,
which is when I posted the link above. It wasn't long afterwards that
you came up with your last hack job.


This is

has a lower drop... and hogs.


I don't see two diodes in parallel. Time to lay off the sauce, Brian.

Frank... I didn't say the diode scheme didn't work... I said it didn't
work well. Actaually, the Motorola RF Data Manual shows this scheme in
many of their designs... so maybe you give them a call and let them
know how foolish they are... lol
But seriously, the diode thing isn't worth the trouble unless you are
willing to hand-select components that go alaong with that circuit.
Even then, it's certainly not the best method. By the way... the diode
tracking scheme does try and use two diodes in parallel. Sorry you
don't see that... but that's how it is... and why it doesn't work
well.
