Dick,

That's a heck of a lot cheaper than here in the states.
Esentially, the monthly charge here is renting the transformers,
even though you pay the large fee to have them hung on the pole
and connected to the service you install (they are good enough
to give you three meters LOL). In the US, they nickel and dime
you to death, especially every little tax they can think of.
And to think, we fought the Revolutionary War over not wanting
to pay taxes to England! Here, the poor pay the tax, and the
rich prosper. I'm all for a flat tax where everyone except the
ones under the poverty level pay the same percentage. I'll never
see it in my lifetime I doubt.

Best,

Will

Hi Dick,

That's not what I've been tolled by Eneco (power company)
in Capelle aan den IJssel when I moved into my new house
2 years ago. I forgot the actual quote, but it was more like in
the range of 1000.

Cheers,
Sasha YZ6X/PA

All,

I have a HP 412A VTVM coming in, and I'm wondering what others may
know about these? Anything I should look for, etc.? These don't have
the rectifier tube in the probe like the 410 models do, but supposed
to be as accurate by what I read from an old HP catalog reprint.

Also, I still have a few pieces of test equipment for sell. I'll sell
these seperate, or all together. I have an Associated Research Hypot
4kV $40, a Megohmeter by Freed Transformer $20, a B&K audio generator
$15, and a Data Precsion 5-1/2 digit DMM $20. Or, I'll take $65 for
the lot. S&H extra. I'll e-mail photos to any interested.

Thanks,

Will

Denny,

A rotary converter (pony motor) is the only way to do it correctly. A
static converter is simply a started capacitor bank to get the motor
up to speed then it drops out letting the motor run on just two of its
three coils. You loose 1/3 of your HP over it too. With a rotary
converter, you have all three coils running and all the HP rating.

When you put a 3 phase service in, the $2 grand was for the
transformers (45-50 kVA) and the incoming lines. One has to buy the
service entrance (conduit and pecker head), the wire, the meter base,
the conduit into the building, wire for it, ground, and the breaker or
fuse box. Then run wire to that. It can cost a good bit more.

Best,

Will

Sounds like a Smoke screen to me.

I felt the same way!

One doesn't need a

"The thing that gets Rich Measures in trouble is that his
writings HAVE been peer reviewed and been denounced as snake
oil by academics, responsible engineers from every major tube
builder, RF design engineers from many companies ranging from
amateur manufacturers to MRI/ISM amplifier builders and
several major broadcast transmitter manufacturers. Measures'
material has all the earmarks of a "good con" ... just enough
truth to give it a patina of believability to the untrained
and impressionable".

This all over Tom trying to argue that a control grid could
become positive.

It can and definitely does so in a grounded-grid amplifier during
most of the negative half of the driving cycle.

No, If you remember, I did say that that was the only case.
What he was getting at was it could become positive with the
grid disconnected from ground, and if I remember, there was
another way which we both collared him on.

It may be less negative than the cathode, or one
might say it's more positive than the cathode, but it sure can't

be

positive with respect to ground or 0 Vdc!

Ground Is Not the reference point for grid potential, it's the
cathode. Example: If the cathode is neg. 1500v (to ground) and the
grid is neg. 1490v (to ground), the grid potential is positive 10v.

Correct, I'm not saying that and agree, but it is all still
negative with respect to chassis ground or the 0 Vdc point.
It could never be positive in respect to it, especially if
it's tied directlly to it. Remember him saying a grid could
become positive when being bombarded by electrons, especially
if it were disconnected from ground? That was when we were
discussing grid fusing. I think the moderator figured by me
saying Terman meant less negative was me questioning peer
reviewed authors. Though, I quoted Termans exact words saying
"less negative". The thing is, that is what I quoted from the
handbook I have. What Tom quoted wasn't from that handook I
have found, as there was only one edition of it, I looked. It
was from a similar book that Terman wrote which had three
editions with a similar name. I figure now Terman worded it a
little different so as not to come under the same trouble as me
describing it. I still see it as less negative than the cathode
which in reality it is (compared to ground), but by it being
this way, it creates a positive or more positive potential.
Tom though, said the grid could be positive un-connected from
ground, and if I recall, another way besides being driven that
way.

I bet I had 30 e-mails come
back to catch Tom saying this. He would argue until his last

breath it

was positive. All because of something he read, and because he

doesn't

understand theory enough to know better.

Rauch is right on this one, Wil. However, he is not always right.
His Achilles' Heel is that he sees himself as a RF infallible
"expert". Thus, he is the last person you would want for the job of

See above

censor in a discussion about RF Tx amplifiers.

Editorial -- The only kind of discussion that works well is the wide

open kind, where there is no censor-librorum/moderator/

administrator.


It's the only way to get at the root of a matter and find the truth.

What put the icing on the cake for me was when Tom commented on a

post

I made about determining the rms current a transformer needs to

supply

to a FWB cap input supply. Tom replied I was wrong, and that it

was

garbage (No wonder why some Ameritrons are poorly designed). When

I

sent back a reply, with a link to Hammond Transformer website with

the

same formula, the un-named modeartor wouldn't post it (censored

it).

In other words, he was hanging me out to dry to look like a fool

over

not letting Tom be wrong.

That's why Richard George reasoned that Tom was most likely the
unidentified Administrator/censor.

I reasoned the same myself, but still can't prove it. Someone
claimed they knew it wasn't Tom, but I'd like to see proof. If
one is ashamed to, or to scared to show who they are, they don't
need to be a moderator.

Well, that was it, I started by-passing him
with direct e-mails to the members that I had in my address book.

The

rest was, well history. ; )

With Tom, The cardinal sin is neutralizing his control over others.

He sure has his control in this moderator. A lap dog, he for
sure does act.

Then, if we talk 3-phase supply and 6-puls rectifying,
lets say around 5 kV DC potential, how much glitch C
is needed to achieve 1.5 percent ripple?

### Dunno. You would only have 5% ripple with NO cap.... and
with a resonant choke set up.....you probably wouldn't need any
C at all ! [3 phase]

### IF no resonant choke setup... and just a straight C input
filter.... I'm guessing around 5-16 uf would be plenty. It
would also highly depend on the load.

### I haven't found any formulae for a C input filter HV
supply........ with 3 phase. I don't have access to 3 phase....
so never pursued it. It would be the ultimate setup. IF you
find anything... let me know... as I'm most interested. Somebody
is going to ask me to engineer one for em... so I had better
research it.

### I did see some info on C input 3 phase HV supplies some
where.... it's in Orr's older books.... but not alot of info.
Seems to me he had the 3 x primary's connected in a "Delta".....
and the 3 x secondary's tied in a.. "star". The rectifier set
up... if I remember, sorta looked like just 2 x diodes per sec
winding... one flipped around If I remember. The RMS voltage
per sec winding vs no load HVDC output is what threw me.
With say a 1 kv sec.... I'm positive... the OCV hv wasn't 1414
Vdc. [I may well be wrong with this.. just going by memory]

Yeah, that's what I am doing... We quickly metered the remaining
four... They are good, but two had drifted out of the 5% range a small
amount and two were still in range... Each one is dissipating ~20
watts which should not age a 100 watt too terribly... They are mounted
vertically on bent finger stock, so air can flow up the center of the
tube as well as around the surface... I do not see any glaring faults
in the construction... Certainly, if a winding has a nicked/kinked
wire it will spot heat and fail over time.. If the wire has
inhomogeneity inclusions these spots will also heat... Could be a lot
of reasons for a spot failure...

Been watching the 3-phase discussion... Long ago and far away I was
the companys 'expert' on 3 phase 15,000 volt substations and 480V
distribution system, power factor correction, yadda, yadda...

up... if I remember, sorta looked like just 2 x diodes per sec
winding... one flipped around If I remember. The RMS voltage
per sec winding vs no load HVDC output is what threw me.
With say a 1 kv sec.... I'm positive... the OCV hv wasn't 1414
Vdc. [I may well be wrong with this.. just going by memory]

I wonder if 'Z' is the c.s. administrator of the old amps group on

Could well be.

Har, he really shot himself in the foot. He's now
the administrator of a defunct group. He might as well retire, he
won't have anyone to administrate to now but himself!

Hey 'Z' is your name Tom?

chortle. The laugher is that the "Administrator" / censor who jackboots folks out of AMPS for not giving a callsign, does not give a callsign himself.

If Tom joins this discussion group, I would definitely not be disappointed.

Will, et al,
I challenged the 'administrator' about what calls for being banned from the list. Included were email lists and having a 'lack' of a call sign. Neither one, I pointed out were part of the list's own rules/regs. But that was another day. I'm about ready to "vote with my feet." My only regret is that it isolates some very good technical knowledge that hasn't found its way over here (yet).

Some of those with good technical knowledge are Tom's pals. My take on Tom is that he attracts people who share a common element in their childhoods. Apparently, the attraction is so strong that a number of the technically enlightened will not comment about statements such as Ni-Cr alloys have reverse skin effect at HF.

I know of several that tried and the post never made it. Two did, but
the rest went bye bye. The unnamed, "no-callsign either" moderator,

chortle. My guess is that his callsign is W8JI since W8JI knew why I was booted out when no one else did. Also, the posts I wrote that questioned Tom's questionable technical statements were censored like clockwork.

who was on me about showing a callsign, has his eye on every post that
comes into Amps mainly to protect one person for any, well lets say,
embarrasing moments.

Indeed. If it walks like a duck, and it quacks like a duck, ... ...

When a groups moderator censors others posts who contradict one that
is plainly wrong, allowing the wrong comment to show, and not the
correct one, it's not a place to be.

Indeed. However, AMPS was started to protect Tom from what happened on rec.amateur-radio.homebrew in Fall, 1996 - where there was no censor to throttle those who questioned Tom's technical missteps.

Correct being that the one
posting it actually knows what they are talking about! : ) It's even
worse when the moderator lets the one in question take pot shots at
others, and when they reply, the post gets canned before the others
can see it.

The founding fathers of the United States thankfully realized that Censorship is poison.

Now, I admit, I was one of the ones that was guilty of e-mailing
everyone in my address book and bypassing the moderator. The moderator
aimed that one admonishment about harvesting e-mails at two people,
Rich and myself. However, this moderator must think that neither of us
has an address book on our own without his so-called "harvesting"
going on. I thought I still have the right, by the 1st amendment, to
e-mail anyone I damn well wish. I'm not aware that has EVER been
changed.

Moderators/censors/control-freaks dislike being bypassed because it neutralizes their control over others.

Sincerely,

Will

Yes, that is the distinct number of people who claimed to have
attempted to post it and claimed that it was not posted.

I heard from others who said they tried to post the info about the
new group and it did not not get past the censor.

Thank you for the corroborration.
