Imagine an alien species in which, when someone dies, all of their wisdom and knowledge passes directly to their offspring. That efficient preservation of experience enables the species to progress at a phenomenal rate. Sadly, when humans die, our lifetime of expertise is lost. At best, we can only try to educate our young, each time starting over from scratch.

After decades of head scratching, chin rubbing, and extensively consulting the Magic 8-Ball, experts now agree that there is no such thing as a free lunch. However, somewhat unexpectedly, we now have free TVs. If you guessed that there are strings attached, you would be correct. Very correct.

Of course, you have a wall of discs. And what an impressive wall it is. LPs, CDs, DVDs, and Blu-rays. There is no better feeling than firing up the home theater and sipping on a martini as you casually peruse your massive collection, pondering which disc to deploy. Moreover, with Vudu to Go, you can take the wall with you anywhere you go.

I love tubes. You love tubes. Everybody loves vacuum tubes. Of course, the ultimate vacuum tube is a cathode-ray tube — the glowing heart of good, old analog televisions. What a cool invention — a device that can input electrical signals and convert them into visible moving images. Hmm — would it be possible to build your own CRT as a DIY project? You betcha!

A purist can be defined as “a person who adheres strictly and often excessively to a tradition.” I would add the corollary: particularly when it comes to analog audio. Which brings us to today's DIY project: Building your own audio amplifier from scratch. With vacuum tubes, of course.

You mow your own grass. You shovel your own driveway. You make your own granola. You grind your own coffee beans. You chop your own firewood. You change your own oil. You reload your own ammo. You make your own vacuum tubes. Wait. What?

The TV business is lousy, right? Companies are getting out of that market like it was a house on fire. Just last week, we reported that Sharp is leaving the Americas. It sold its Mexico plant and name and rights to Hisense for a measly $23.7 million. Sharp follows Toshiba, Hitachi, Pioneer, Mitsubishi, Philips, Magnavox and Thomson in divesting and selling its TV interests for fire-sale prices. The TV business is lousy, right?

So, how would you like to buy a piece of a TV company?

Vizio recently unveiled its new P-series models. And they are pretty impressive, featuring 4K UHD and the very cool SmartCast app that essentially builds in all the capabilities of Google Cast. Since they are Vizios, they are very competitively priced. Very nice. The problem is, if you want to be a stickler for details, these devices aren't actually TVs.

Has this ever happened to you? You are surfing on your laptop and suddenly a scary screen appears, demanding ransomware payable with your credit card info, and 3 bottles of vodka. The same thing happened to me, except I was watching TV and instead of demanding that I send money, a pop-up on the TV screen offered to send money to me.

70 years is a long time. Few companies make it that far. Klipsch, one of the survivors, and a storied company at that, is now under the VOXX corporate umbrella, and VOXX is celebrating its 70th anniversary.

You've done the factory tour at Zuffenhausen. Eight times. You once got in a fight and lost a canine, defending the IMS bearing in your M96 engine You patiently explain to newbies why the ignition switch is on the left side. Of course, you have "911" tattooed on your bicep. And, you just bought a Porsche Design soundbar.

You probably have at least a passing awareness of James May. He was one of the trio who hosted Top Gear (recently reincarnated as The Grand Tour) and is a bona fide cool car guy. But he has also hosted a variety of interesting, verging on odd, television shows. Perhaps the oddest show, and my favorite, is The Reassembler in which Mr. May, well, reassembles things.

It is a fact that we all exist on the spectrum. That is, the spectrum of individuality. At the top of the spectrum are those rare individuals who are one of a kind, the nonconformists, the rebels. At the bottom of the spectrum are the common and docile ones, the sheeple. Where do you want to be?

You can tell the age of a tree by counting its rings. You can tell the age of a person by counting the number of times they say something anachronistic. For example, if I start talking about Compact Discs, kids will instantly identify me as being, uh, mature. They will make snide remarks about the La Brea Tar Pits and mastodons. Kids can be cruel. Ask me how I know.

With all due respect to sloths (arboreal mammals that hang upside down from trees) we (humans) are total sloths (ie. reluctant to work or make an effort; lazy). To prove my point, your Honor, I submit Exhibit A, those red Netflix mail-in envelopes.
