Even if you HATE Ebay posts - just look at this thing!

It's the most horridly constructed piece of gear I think I've ever
seen - at it runs 2KV and half an amp!! LOTS of photos and
description at the above link.


Wellll... Technically you are correct, but had it been a transmitter I
might have been able to have given you a run for the money.

I built my first "homebrew" transmitter using the parts from a TV
chassis. Not the chassis of today, but back when TVs were all tubes
and used a chassis about 2 foot square and 3 to 4 inches deep.
The power transformer was quite a bit bigger than the ones used in
any of today's 100 watt output rigs.
I built the old standard 6AG7 Oscillator with a pair of 6L6s in the
final. I've forgotten if it used a separate driver. At any rate it
was built in one corner of a stripped chassis. Looked kinda lonesome
in there.

It worked, easily ran the 75 watts permitted to a Novice back then and
it was *big* albeit with a center of gravity a bit off center.

Later on after moving up to a Viking Ranger, I stripped all the parts
out and used a 12AT7 as an electronic TR switch. Just one little tube
and that big transformer in one corner of that big steel chassis. I
was able to set the transmitter on the TR switch with lots of room to
spare.

I bought it in '96 for the parts, but have kept it in my own shack
all this time just because it is SO UGLY in a very fun way - it's
like every possible example of how NOT to build something,
and come close to dying in the process. Unbelievable. This
is the definition of a 'widow maker'





I'm hoping someone will buy it to keep it together for the fun
of it, instead of gutting the parts. I am liquidating my shack
(and most of my other clutter too) and don't want it anymore,
but ya GOTTA see this thing! It really is a sight to behold.
And for GOD'S SAKE don't plug it in! I don't even want to
be in the room if you did!

Thanks for looking, and please don't take offense at my post.
