So this would be an oft used Usenet tactic, Vis-à-vis;
a) First, manufacture a claim and then infer that the other combatant
made it.
b) Then others may use that false claim as a justification for further
criticisms, attacks and/or allegations of arrogance, pseudo
intellectualism, whatever. At this point it is open slather.
c) Never-ever concern yourself with the truth of what claims the other
combatant did ACTUALLY make about their expertise or lack of it. This
would be sheer folly and may lead to the loss of the argument.
Regarding your suggested methodology. Making the suggested
measurements reveals nothing unless it is done during periods of
voltage overload. So OK, I could pull the DMM and quietly sit there
and wait for a hours, perhaps days, poised with my probes at exactly
the correct location and angle and just wait for something to happen.
Yes, I could do that, if I was a creation. Well done.
Regarding your assertion that I don't know "how challenging it is to
design and implement what you wanted". Well I certainly don't know
how difficult it is for YOU.
As it happens, I am one of the few contributors here who has ACTUALLY
suggested a viable and cost effective solution to my own request. Go
on, look back. I DARE YOU.
I am not being conceited here, I actually EXPECTED that I could get a
better solution from someone here.
Re: Your analogy. Could I suggest you reproduce it in another post
and I will go over it with you, point-by-point. This post is already
approaching an unmanageable size and in any case your 'analogy'
amounts to little more than 'white noise'.
Re: Bob's advice. It may be good advice. The likelihood of getting any
useable information from a .Usenet thread is inversely proportional
to its length. So the longer this goes on, the more likely it is good
advice.
Also, I don't know where you got that 'Pre-amp' presumption.
Certainly not from me.
You reckoned that if I was being honest I would say "Actually, I
built the engine, it's running badly, does anyone want to buy some
really good fuel filters?"
The natural presumption from that statement is, according to you at
least, that I would be dishonest if I claimed:
a) Not to have built it,
b) That it is running well (except during periods of over supply)
c) That I don't want to sell my caps.
However, all those things are true. So that is the first reason why
your analogy is fucked up and arse about.
I made no claim about making it, or designing it for that matter. I
did tell you that I had swapped some capacitors, which is only a
minor modification at best. I was a little surprised that nobody
suggested checking for dry joint(s) on the caps, but hey, that is
your prerogative.
Regarding this statement: "I thought my insightful analogy would help
you understand why people responded to you with derision".
I developed my own theory, days ago. Read my functional description
of the supposed club of 'deciders' that I have dubbed
'Phil-o-philes'. My theory much stronger that yours because, like all
good theories, my theory is based on verifiable, empirical
observations of facts. (i.e. when Phil inferred that the power to
"get to decide what others accept or believe" exists as a right that
some people may hold others not. To make such a distinction, he must
believe that the power a) ACTUALLY exits b) is assignable to various
individuals and to the exclusion of others, which is as much as
saying, he believes it exists as a RIGHT. He didn't say on what basis
this right might be bestowed on individuals, but we can only assume
it is earned by displaying superior knowledge or experience.
On the other had, your analogy is based on what? Three complete
falsehoods for a start and then no empirical observations that you
have elucidated thus far.
Your analogy is NOTHING more than OPINION, masquerading as analysis.
Perhaps you may develop it into something more useful, but thus far
it has the appearance of analogy by a 'petrol head', and nothing more.
Regarding your apology: I will give it my consideration.

Well, I didn't think of searching for the '7815 datasheet', so
fucking sue
me.
That shows that you are not experienced in working with electronics -
anybody who regularly does searches for component numbers would
automatically add "datasheet". Furthermore, anyone with electronics
experience would understand the operating characteristics of a common
linear
regulator without needing to refer to a datasheet - it's really
common, basic stuff.
Either way, the cheapest solution is sounding like I should
exchange the 7815 /7915 pair, for a pair that DOES have that 30V
spec. and in so doing,
eliminate the possible cause of the observed clipping during voltage
overloads.
The first thing to do is measure voltages at key points - at the
output of the AC plugpack at the input of the regulators, at the
output of the regualtors etc. Boring I know, but that is how you
start the diagnosis a power supply problem. That you don't appear to
realise that really basic fact demonstrates a lack of knowledge and
experience with simple power supplies and suggests that you're not
equipped to diagnose nor fix the problem.
Also, I take umbrage (offence, to you) at your trite analogy. It
isn't an
accurate portrayal of what happened or my actions or my motivations
or my attitude. I would welcome a point-by-point comparison of your
analogy and my behaviour.
My analogy, horribly misspelt as it probably was, was reasonable, if
not as
amusing as I would have liked. You clearly don't get how challenging
it is to design and implement what you wanted - it's *really*
complex stuff. By comparison, getting a standard dual-rail, linear
regulator power supply to behave is trivial.
The more I think about it, Bob's advice is correct - you should get
someone
with a solid background in electronics to fix your preamp for you.
Your PRESUMPTION that I must pay too much for my Black Gates is
based on what? An ASSUMPTION that I pay foolish prices. That is
both insulting AND ignorant (of how cheaply Black Gates can be
purchased).
Hey, if they give the sparkling audio performance you like, fair
enough. I probably haven't paid enough attention to the musicality
of the caps I buy.
I also take umberage to your allegation that I am not "being
straight-up with [this group]".
You reckon that if i was being honest I would say "Actually, I
built the engine, it's running badly, does anyone want to buy some
really good fuel filters?" Here is why I wouldn't say such a thing:
a) I didn't build the application, I modified it.
You never said that. It does explain a lot. In my analogy, it would
be like
revealing that you'd modified your engine while at the same time
giving the
strong impression you don't really know how engines work.
b) It isn't running badly (under nominal conditions), it sounds
superb. c) I am not SELLING anything.
That was a joke. Sorry. I was kind of thinking that if your "thing"
didn't end up working, you could recover some cash-money by Ebaying
them fancy caps.
I look forward to our point-by-point comparison of your analogy
with my behaviour. I can't find many comparisons at all. Do you do
this often? (that is: make up stupid analogies that just don't
work).
Look, I've got nothing to add. I thought my insightful analogy would
help you understand why people responded to you with derision.
Obviously you still don't get it, and that seems to be because you
don't have the knowledge and experience in electronics to diagnose
and solve the fault - everything you say reinforces that fact.
Get someone who knows what they are doing to look at your device. If
it's a
power supply problem they'll diagnose and fix it very quickly.
And you might be able to pay them in capacitors
