Not quite as crazy as a 250kW transmitter tube, but mad enough

Ah, now a reason to build that Class AB1 audio amplifier with the
4CV250000Bs in the stock room.

Hey George:  I had a great time as well!  Glad you made it back safely.

The big news at the cedia show was "4K Ultra HD," formerly known as 2Kx4K.
Sony had a beautiful 84" 4K tv being driven by the (included in the price)
4K media server device.  This is four-times the resolution of your
soon-to-be-obsolete 1080p HDTV.  Incredible picture.  A mere $25,000.

But the priciest thing I saw at the show was an 8-foot-tall awesome speaker.
I asked how much power it could handle, and he said 4000 watts was no
problem, and that they really just don't make an amp that can drive it too
hard.  It is $200,000, but hey, that's not just for one;  it's for a pair!

GreenKeyers - - -

Got back here about 8 PM Sunday night.

If there are any questions or problems with Fire Sale Items, call or 
e-mail me and we'll address them "mosh-kosh" (old Navy term meaning 
IMMEDIATELY).

Had a blast with Gil, the Intrepid Moderator, at the electronics 
show in Denver.

If you have a couple million bucks and need a transistor radio, 
they'll take your money there.

Gil and I regaled each other with sea stories, land stories, 
GreenKeys stories, guzzled beer and wine. (2 coronas for me,
3 goat bladders (Glasses) for Gil), declined offers of personal 
services from several not so pleasant appearing street people, and 
watched the human powered and horse-powered tour services haul their 
joyous cargoes up and down the street. The food was good, and the 
conversation excellent.

Thanks so much Gil, and when you set up your new factory in Sequim, 
I wanna be the janitor!!!

Left Delta,Colorado about noon Saturday, and meandered back here all 
day Saturday and most of Sunday.

Unwound yesterday, and today first real task is to replace the 
alternator in the van. It growled at me most of the trip but 
faithfully made enough juice to keep everything running.

To paraphrase Mel Brooks, "It's GOOD to be the King, But Much better 
to be HOME!!!"

Now everyone will please raise their flagons with a "Hear, hear, Mr. 
Gil" then continue GreenKeying..

George - W7TTY
