largest glass tube
 

Hi Folks:
A guy at work bought his old guitar amp to get looked at. The
tech said he needed new tubes. (probably really doesn't). However, I
needed to bring in my 833A and said he needed 2 tubes like this!! He
was hysterical!
The tech and I got talking about BIG glass tubes. I was wondering if
anyone knows of a bigger glass tube than 833a , 852 , 861, 4-1000a
etc.
Thanks!
Harry

Well, there's a ham who has a website of pics of his full-gallon rig,
with one _BIG_ Russian glass tube as the final, all out on 2x2 and 2x4
supports. I don't have that, but someone might remember it. It looked
like the tube was about 18" high.

actually walking up and pulling the trigger starts to fall into the "Why
Bother?" category. -- A deB, in the Monastery

The 849 comes close, if I recall the number right. When I was a kid in the
50s, our family knew the guy who maintained all the local airport radios. He
brought me a lot of weak or blown tubes. The 849 was a classic -- over a foot
tall, big metal plate cap. The filamanet was a wispy M shape held up by little
spring-loaded clips on the ceramic frame inside. The tech said they only ran
it about 150 watts, so it would last a *long* time. Probbly used in the LW
beacons.

ISTR people made table lamps out of these bottles. 73, Mike K.

I have a few 849's around here but my biggest tube is an Eimac 750

These are pretty big. They're described as 5 feet tall. They're from
Powel Crosley's 500 kw WLW transmitter:

THE BIGGEST I EVER SAW WERE IN A 150 KW TRANSMITTER IN GERMANY. THEY
WERE TALLER THAN I WAS AND ABOUT 18" THICK. TWO OF THEM SUPPLIED THE
CARRIER WITH ONE OPERATING ONLY ON PEAKS. THE EMERCENCY POWER WAS
SUPPLIED BY A DIESEL RAILROAD ENGINE. WEISSKIRCHEN GERMANY WAS THE
LOCATION. ANY OLD AFNERS AROUND.

Bill Turner, excuse caps, short answers, stroke.
Business SASE, each order a copy of The Pocket Resource Guide.

Ever seen the finals for a commercial radio station transmitter. 50,000
watts use a very large glass envelope.

Wow! Thanks! Cool pics! I'd like to find something like that on eBay!
It sure would make a neat lamp, or tesla coil!

There's a bigger one too, but I can't remember the URL. It was used by
an American propaganda station beaming programming to Cuba, IIRC. It's
all glass, about 6' high and was a self-contained oscillator and 500KW
power amplifier. Only three were ever made.
