Design Error Time is Up

[Phil Allison]

Hi to all the rocket scientists here:

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

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 !!

You seem to be saying that you wouldn't want to belong to any club that
would accept you as a member.

If all your "fans" are fools doesn't that kinda make you president of

Not strictly true. Win Hill and I admire your technical expertise.

Bitrex is forty and has yet to run into "not invented here"?

Fault-finding is a very useful skill when you can sell it as "trouble-shooting".

When it shows up inside an organisation, the people who do it tend to get seen as "excessively critical" and as "subverting the chain of authority".

If they go public they are "whistle-blowers".

Getting paid for it usually involves them getting "what they deserve for trying to make me look like an idiot". This isn't money, though it can involve paying money to enforcers - not always lawyers.

You can hardly do worse than threaten someone's income or career, no matter how dishonesty they are making money and how much you are being damaged as a result.

in life, feel free to call me a donkey's dickhole all day if you're

You can hardly do worse than threaten someone's income or career, no matter how dishonesty they are making money and how much you are being damaged as a result.

The joke is that if they listened for long enough to learn how to earn money more honestly and do less damage in the process, they'd almost certainly make more money.

Good products are easier to sell. The best products may not look enough like the competition to be easy to sell, but getting the bugs out of a barely adequate product has almost no downside (unless previous customers expect cost-free up-grades).

Speaking as a senior citizen, I have to agree.

They tend to have seen enough to be well aware that getting enraged isn't worth the effort.

It is unfortunate that complacent youngsters ignore good advice - even when it comes from people of their own age.
