Well, yes, because you had a speaker as a load, any DC-output-distortion was going to be a problem.

** Huh ?? What speaker??

For a rocket scientist, though, the load might NEED some DC to operate well;

** You one illegal drugs ??

it's

not a 'bad amplifier' so much as a 'mediocre fit to the driven load' .

** Like an undersized hat on one's head ?

It's common in audio to design some output impedance in an amplifier,

** No it isn't.

and rocket

scientists do NOT understand why anyone would do that... because they
don't expect to hunt for dead fuses with an audience waiting...

** I have read this load of poop 5 times.

Not a single word makes any sense.

WTF is this raving lunatic even talking about?

No, you can't take it. I have been shot, robbed, kicked half to death and all that. My Parents got divorced and later Ma told me to go to hell with my Father. And then his last words to me were "Get the fuck out". Died the next day and NO, I didn't kill him.

One wonders what made Phil how he is. Maybe every time he said pass the butter at the table they kicked him in the head...

While you aren't as verbally abusive as Phil, you often post remarks that make little sense. The above is an example. You say that I can't "take it" and finish the paragraph talking about your what would seem to be crappy life... as if somehow the two were connected. Obviously in your mind they are connected, but what you wrote totally fails to make any connection.

I often don't read your posts because they are frequently, but not always, full of irrelevant and illogical thoughts. Sorry, that's just the way much of humanity would perceive you.

** So a happy childhood ?

Believe me, it shows.


One wonders what made Phil how he is.


** High intelligence and fearless honesty.

Raised as a catholic, where lying is a sin.

Then they lie straight at you, so you get to despise hypocrisy.



.... Phil

The same happened to me. Some people get over it. Obviously you didn't.

Yeah, some people learn to enjoy being beaten.

Sometimes lies and hypocrisy happen not because someone is trying to be
malicious but because they're trying to be kind. Not always, sometimes.
And it doesn't always work out to being legitimate kindness in the long
run, but people don't tend to look at the long run.



** Does this sound like a half witted, drug fucked rant to you ?

Does to me.


..... Phil

Yes, Phil. You write as if you are on drugs and ranting. As usual.

** Totally off with the fucking fairies as usual.

This NG is now infested with know nothing morons and scumbag trolls like him.

Topped off by the " Three Stooges" who cannot analyse a simple audio circuit to save their lives.

Strewth.

I believe my point is now VERY well proven - it is nigh impossible to
identify design errors by just looking at the schem.

What instead happens IS folk see GHOSTS - perfectly good designs are
condemned as being flawed in some nonsense way.

Mostly for the simple reason that the arm chair experts have *never seen*
one working - necessary to discover how wrong they are.

And even that experience would not convince all here of their dumbest ERRORS !!

----------------------------------------

Finally:

The Yamaha P2200 has a badly designed VI limiter - it does a fair job of
protecting the output BJTs but prevents the amp from driving even average
speaker systems with a 4 ohm nominal impedance to rated power.

A two minute, back of an envelope calculation reveals that fact - IF you
know how to do it and what the result needs to be.

This article, by me published 20 years ago, tells the whole, gory story
and describes easy to do tests that characterise the issue and give a
pass / fail rating without risk to the amplifier concerned.

Fig 4 shows how the P2200 reacts to a 5.6 ohm inductive load with 45
degree phase angle. It is not the worst example of this - the huge, heavy
Bose 1800 is twice as bad reacting to a 12 ohm load in the same way.

IMO, only Bill Sloman got even close.

Lastly:

Me post something I designed HERE for the Three Stooges and assorted Rocket
Scientists to pour scorn on ?

No bloody way !!

--------------------------------------------------------

Only the strong possess the fortitude to post their own designs to this
group. Designs that include both a schematic diagram and documentation
that explains how the circuit works.

Kindness was hard, and it was the preserve of true strength."

Thank you, 73,

On this horrible NG ??


As Basil Fawlty famously said of his lone, satisfied customer:

" We should have him stuffed".
