What happened, and you may well know this, was that when Tom first
came back on the mailer, Rich and myself collared him on several
topics he was really wrong on. When we done this, the unknown
moderator placed Rich and myself on moderation. The lazy b@st##d would
only post Rich or my replies maybe twice a day either early in the
morning, or late at night. What brought the thing to a head for me was
Toms reply to me about how to figure the rms current needed by a
transformer from a bridge rectifier with capacitor input circuit. Tom
had replied that I was wrong, so my next post proved me correct, with
a link to Hammond Transformer showing the same formula. This unknown
moderator would NOT release my reply to the list because I proved Tom
wrong. I then took the advice of Rich and started going around this
moderator by direct mail. That's when it came out on the mailer about
"harvesting e-mail addresses" which I never did. I did however send
that reply for Tom to almost everyone in my address book. The
moderator really got pissed about this. He finally took me off
moderation about a week later, but did not Rich. Next, he silently
banned Rich from the group, and a member posted about Rich being
banned. The rest is history.

I also received a very bitterly written e-mail from this unnammed
moderator about Rich and myself. I have to say, it was to the point of
liable. The rant sounded a lot like Tom by the words and expressions
used in the text. I then e-mailed the letter to Rich and a few others
who wanted to see it. That's when we first started wondering if the
moderator wasn't Tom.

### I also noticed that once the dust settled... that W8JI is
back at it again...... posting left, right and center...
on 'amps' !!

Yup, and the shame is that ones not knowing any better will believe
some of the theory he's just plain wrong on. I finally added Tom to my
junk mail filter and his posts end up in the waste basket in my e-mail
application. I noticed he was really taking off as my junk mail folder
really grew in the past 1-2 days, all from Tom.

### some poor fellow wants to build a hb tube amp.
Tom.. 'suggests' he build a 12 vdc SS device.

Talk about splatter without using a filter, and the guy will be extra
good friends with his neighbors.

### If Tom Rauch is not the admin/censor of 'amps'..... then
he's certainly joined at the hip of whoever is... or has a huge
influence over the ...."mystery censor" .

AMEN!!!!!!!!!

### Rich tells me... that the mega mailing list is now defunct
on 'amps'. To me... that's the straw that broke the camels
back.

### IMO... 'amps' has just degenerated into a ... "Tom Rauch

Exactomundo!

## In the past..... anybody who didn't have a callsign got
booted from 'amps'...... ditto with some very knowledeable
11m amp builders...... and also Carl, KM1H.... who was a wealth
of practical info.

Yup, the moderator said in his e-mail that since I didn't post a call
sign, and used to build illegal amps back in the 80's, he gave me
plenty of leway. I had to laugh as he didn't post a name nor a call
sign himself!

Ed Dullaney who owned D&A Manufacturing was who talked me into the
business right before he passed away (Actually two others did to which
will remain nameless). We became good friends and spoke a lot on the
phone. Ed actually was a teacher at a Vo Tech, and was an instructor
for an electrical corrospondence school. He used to be pictured in
some ads for the corrospondence school in some old electronics
magazines. Ed was also a Ham by the way, and knew a great deal about
amplifier design. I like him give my hard earned knowledge of amp
design free to anyone who asks. Just because we built illegal amps at
one time doesn't mean we can't offer free knowledge to others.

### who ever designed the undersized tank coils in the AL-80B
was a complete idiot imo. The wire ga is the same size as
what's used in a 200 w Drake T4XC TX.

IMHO, about everything they have as far as amps has been copied from
other manufacturers (IE: Heathkit, etc). This, including the mistakes
of before. Tom also evidently claims to have worked for Heathkit, or
was close with the designers. I really think that is a bunch of hoopla
myself. He may have spoken to a few, but I don't think he ever worked
for them. When Rich asked him about his association on Amps, he
declined to answer.

Doug

I think its unfortunate how most ham radiogroups have evolved in to
some kind of cult worship society or worst product worship society.

As I see it, guru worship with a large pack of yippy lap-dogs takes the cake.

It seems some forget what the purpose and aims all these groups are
for, that is that they here to foster the spread of knowledge.

To me, passing along what we OTs have learned is worthwhile -- despite the hairpulls with censors and "experts"..

What we have on many ham newsgroups, are some very well meaning
characters who go beyonds the stated aims of groups.

Well meaning people are not into being worshiped.

The most annoying thing about ham groups is the request for a
callsign. Now since when do you need a callsign to use the internet?,
or when you need to show your drivers license to join a car
discussion group? This form of moderation is under the guise of
wanting to control spam, which is nonsense.

Indeed. After Bill was gone, Tom ran amuck.

To me the content of the
post to newsgroup should determine its value. Why many want callsigns
is so that they can indentify the person posting for personal attacks
in most cases.

If technical editing is required why not let the members of the group
select a few technical moderators, if 10 agree the post is garbage
then it can get deleted.

If a post contains technical garbage, better to let the members who know better critique its author.

I have obtained a Drake L7 amp from an estate. It had lightning
damage to the power supply. I need to replace a couple capacitors and
diodes. Has anyone rebuilt this supply? I read somewhere on the Net
that a complete board can be purchased from a company in California
but I lost the info. Any suggestions?

Hey Doug, there are a number of people who most likely need to get it

to this point. My guess is that this part of the discussion will blow
over in about a week. Let's be a bit more patient.

------------ REPLY FOLLOWS ------------

I agree 100%, but a distinction needs to be made between "personal
grudge matches" and a spirited debate.

A grudge match is when the party whose conclusion does not add up won't budge.

I too abhor the postings where each side simply calls the other names,
questions their parentage and generally reviles them any way they can.

I welcome ad hominems, expletives, yo' mamma insults and suggestions that I might be doing my helper girl since that usually indicates that the debate has concluded.

That is not the same as questioning the other's knowledge and
application of theory, conclusions drawn or recommendations made.
Those things SHOULD be questioned when appropriate and it often leads
to a heated atmosphere, which I don't mind at all since that usually
eventually leads to the truth.

Indeed. Bill

At the other end of the spectrum are posts which are so bland as to
generate no interest at all. Those also should be avoided like the
plague. Like most things in life, there is a balance to be found.

like "Which end of the soldering iron should I hold when soldering?"

With all due respect Mike, I think you are missing the importance of
these "month-long" debates.

In my view, whenever two highly intelligent and experienced engineers
can not agree on what seems to be a simple issue, there is something
to be learned by the rest of us. The longer the debate goes on (as
long as it stays polite) the more I learn.

Earlier this year there was such a debate on the Usenet antenna group
about current in a HF mobile loading coil. It was fascinating and I'm
glad I followed it. I don't think either side convinced the other, but
I learned a lot.

Keep it up, guys. :-)
