Re: Enough- Now to a Choke

Rich & DJ
 

I sniped off a lot of the original and replies.

Thanks Rich for the reply, I saw the parts for sale but I am try to
build what I can. I have completed a hand made, 12Kv plate variable
capacitor. I know I could buy one but then I can't say I made it.
I have a 1" dia phenolic rod for a form and/or 22mm glass tube that
could be mounted on a dowel to make a choke with. I was hoping to do a
single wind of 20ga magnet wire. If I can do this and all does not go up
in smoke and I feel confident I plan on then looking for a vac variable
plate cap and a band switch and building another one for 40 thru 15, I
don't go below 40 and work 15 the most.
I have an extra socket, chimneys, fil transformer and such for the next
amp.
I built the P/S so it is in its own cabinet on wheels, 0 to about 5Kv @
1 amp. The RF deck will sit on top.

Hi Dick --
Good luck on your 4-1000A amplifier. I built one
back in the 70s and you can see it at:

. <> net/~jpk5lad/4-
1000A%20Amp/4-1000a1.htm

I was going to mention a cost-saver for you since
you mentioned about building your amp a low cost.
Many years ago I read a suggestion, I believe in 73
Magazine, where a fellow suggested using a 1 gallon
pickle jar as a replacement for the more expensive
Pyrex chimney for a 4-1000A. He cut out the bottom
and enlarged the top and claimed it fit the air socket
just fine. At the time I read that I think my regular
Pyrex chimney cost me $12 but I put that bit of
information in the back of my skull in case I ever
needed to have another one or a replacement. So
far I've never had to use it.

You mentioned that you already had a chimney so
you won't need that bit of info either but it might be
worth remembering for something.

The plate choke I used in my amp was commercially
available but I don't recall the manufacturer. They
probably aren't in business now anyway. (Oh no....I
hope that doesn't resurrect the recent thread on the
ham_amplifier reflector which had nothing to do with
ham_amplifiers.)

Good luck on your project. There's nothing quite like
the feeling you get from throwing the switch on a
3500+ volt power supply connected to a newly-build
but totally-untested amplifier. You've heard about
people who saw their whole life flash before their
eyes? That's similar.

I don’t think the Coleman works on the 4/or3-1000 I think its for the
3-500 size. I hope to sneak up on the 3500V , I know it wont tune just
right but I will soft start it with an autotransformer , not just flip
3500v to it cold. Then increase the drive. It does have a standard soft
start set up in the PS.

Re: Transformer page at Wiki finished

Randy
 

Will:
Thanks for clearing that up. I didn't realize that's what had happened.

I read "somewhere" that there's a way to be notified when a page has
been modified. I don't think it's even necessary to be the author of the
page. I'm thinking it was in a print magazine, but I don't know if it was
Wired, Popular "Something", or what.

Thanks for all the effort, 'tis much appreciated.

73,
Randy

Randy,

No, but what editing has happened by 2 or 3 that has contributed has
only been to correct any mis-spelled words and clean up any
formatting. It's all there in good shape. The thing that happened the
first time was the one who authored the Transformers page didn't want
the extra info on actually designing them on that page, and he was
the sole one who did the deleting. Another person from that page and
myself created the one for Transformer design, and a few others
jumped in to help so it's backed up and protected. Anyone can edit a
page, and I hope it might be expanded upon in the areas of RF and
audio/impedance transformers. I wrote everything that is there now
about power transformer design, but left the areas above out for
someone else to do if they want to add them.

Best,

Will

All,

I finally found time to set down and finish the transformer design
page at Wikipedia. I finished several sections and some more on
the
types of iron or alloys used. For any interested, the link is

Re: Enough- Now to a Choke

Rich & DJ
 

Thanks Hal , yes I remember seeing the parts , I guess I forgot to add I
am trying to hand make all that I can. I have completed a hand made,
12Kv plate variable capacitor. I know I could buy one but then I can't
say I made it. I have a 1" dia phenolic rod for a form and/or 22mm glass
tube that could be mounted on a dowel to make a choke with. I was hoping
to do a single wind of 20ga magnet wire. If I can do this and all does
not go up in smoke , I plan on then looking for a vac variable plate cap
and a band switch and building one for 40 thru 15 , I don't go below 40
and work 15 the most. I have an extra socket , chimneys , fil
transformer and such for the next amp. I built the P/S so it is in its
own cabinet on wheels , 0 to about 5Kv @ 1 amp. The RF deck will sit on
top.

Dear Rich,

Look at your reflector archives for the past couple of days.

There's a ham who is selling all sorts of amplifier parts, including
plate chokes.

W2CQM, Ron Lumachi.

He's been on the reflector forever, and he has some great stuff.

Back to Radio / Amp stuff

Hello all you smart people, I don't have any electrical training but I
am slowly building an amp from my junk box. The power supply is
complete. I enjoyed the information about "glitch" protection and did a
cut and paste of all the important notes, making my information list to
build by. I will use a 50ohm resistor and a small gage wire as a fuse in
the HV line. I will also put in a fuse c/t of the filament / bias line.
I don't have much money (retired) to buy but a lot of stuff to build
with. My next thing to figure out is the plate choke for a 4-1000A, I
plan on about 3500v, first test, it nothing goes up in smoke I can later
up the voltage to 4500. The amp will be a mono-bander at first, 21Mhz.
With out a dip meter is there a simple way to build a HV plate choke. I
will not load it to the max , just trying to make something work.

Anyone owning a Kenwood TL-922 amplifier -- I would like to know the part number?of the fan mounted on the back of the amp.
?
Model is a Centaur, P/N:? ???
?
Maybe hold a miror to the back of your amp and drop me an e:Mail off line.

Jim,

Socialism doesn't work, has not ever worked, and will never work for the every reasons you have pointed out in your previous emails.? Anytime you get the government involved in anything, corruption causes things to go to hell.? Government is the biggest source of corruption in society.? It surpasses individuals, businesses, and anything else you can name.? God save us from more big government.? I'll take big business corruption any day compare to big government corruption.? We elect people who think they know what is right for you.? They end up knowing what is right for them.
?
The US had a famous cowboy philosopher back in the 1920's by the name of Will Rogers.??He was a Democrat and probably?some what of a socialist, but one of his most famous quotes was " The people elected Calvin Coolidge president.? He didn't do much, but that's what the people wanted."? I think that's what the people in the US want today.? A president and congress that won't do much. Stop trying to fix things and just leave us along!!!!!

### What's wrong with Socialism ?? Works here. What needs to
be gov't run is stuff like medical/dental/ residential
water/commercial AC power production/ car insurance/ Ferry sytems,
etc. At least that's our idea of.."socilism" You privatize any
of that just mentioned... and prices skyrocket.. and standards drop.

## case in point.... in VE6 land... they had this brilliant idea
they would privatize.. and sell off ALL AC power production. The
idea was that private co's would invest Billions in new power
production. They were gonna chop it up into 8-10 pieces. When
only 4-5 co's showed up... they were surprised... and proceeded
to divvy up the province of alberta into North south east west.
The co's are real happy now. NONE of em compete with each
other... since they have their own turf. None of em are the
slighest bit interested in spending Billions to generate new AC
power. [the provincial gov't there thought with some co spending
billions on new power... rates would...drop]. Instead... there
was no increase in production at all.... rates went up as much as
450 % !!

### In the UK... they did the same thing with their various water
supply's for residential water. Their water rates have gone up
400 % ! They also privatized the construction of new hospital
facilities.... now the consumer is paying through the nose for it.

### cheap electric/water rates means a better economy. You start
paying sky high rates... and the one of 2 things happen.... either
increased production costs get passed onto the consumer... or co XXX
sells up... and moves. In VE6 land... they had foundries that had
been there a long time... and couldn't compete with the province of
manitoba [VE4 land].... due to the huge difference in electrical
rates. The foundries in VE6 land moved to VE4 land.

## If u wanna pay retail + 100%... go for it. Most of us like the
wholesale rate.
