For amusement here's a representative list of some of the _retail_
prices on the parts list for the 1935 Kadette 52 I'm working on:

Tube socket: $0.10
2 gang tuning "condenser": $1.65
5 inch dynamic speaker: $3.50
6-6-6 uF electrolytic can capacitor: $1.35
IF transformers: $1.25
Broadcast/tuning coils: $1.00
Power transformer: $2.35
Cabinet: $5.70

incredibly expensive by today's standards

How do I get the vacuum out of the can and back in the tube, though?

I like that idea. Did you have to wear a space-suit in case any vacuum
got spilled?

I still want my Acme Portable Hole.



   Those have been on back order since 1963, along with their set of
tunnel paints. :(

On the plus side, you can get roller skis now. Instant water available
soon.

Yep. Compared to the 1970s, those parts are at least 4X as expensive. The power XFR seems to be the best deal of the group, less than twice the cost of the IFs.. Strange.

In 2017 money:

Tube socket: $0.10 - $1.80
2 gang tuning "condenser": $1.65 - $29.73
5 inch dynamic speaker: $3.50 - $63.06
6-6-6 uF electrolytic can capacitor: $1.35 - $24.32

ACME products are grossly over-rated. I once ordered the Acme Wildcat and the damned thing mauled me instead of the person I directly aimed it at.

Falling on snow is pretty benign and often fun. Snow is soft and the
coefficient of friction is low. Falling onto dirt and rocks and
pavement might not be as fun.

Did you specify the victim, when you ordered it? If not, it goes for
the fool who opens the package. :)

Skikes are a much better option for most people.
Many rollerskis don't have brakes, or only have
brakes on one ski. Skikes are like roller skis
but they have larger pneumatic tyres, brakes on
both, and they work with normal shoes. That makes
it easier to keep your skin attached.

I have an 11-year-old grandson who is, for all intents and purposes,
_pro_ level at ice _and_ roller-blade hockey (*) He takes some might
nasty falls (he is, as you might expect, somewhat combative ;-), but
he's padded every which way from Sunday.

(*) He is the go-to-guy for the _whole_ league when a substitute
player is needed.

He's the first "jock" that I know of in the family history.

Not sure how they were hyped, but we used them all the time in the 70s
to locate an open tube(s) in series sets.  We kept one in our road
tube caddy; it even used the same "cheater" cord as the TV did.  You'd
be surprised how many low end TVs used a series string back then and
how often a dead TV was an open filament.


   No surprise at all, since I worked in a radio & TV shop at the time.
DIY types would see ads for them, and bug the shop to buy one for them,
even after telling them that it only looked for open filaments.

Not an entirely useless function; probably not all metal tubes get warm
under normal operation. Certainly not all glass tubes do; there are a
fair number of glass tubes whose filaments don't even get hot enough to
glow visibly. Probably in the 1960s not everyone could afford a VTVM or
a bench supply that also had a current meter, and the filament
resistance might be too high to trigger some simple basic continuity testers

Here is yours truly attempting 360's in the features park at Sugar
Bowl:

Well, it's hard to hold a camera and spin at the same time.

I'm about as close to a jock that my family had created up to then
(not very close) but The Brat is a real athelete. I can still out-ski
her just because I'm crazier than she is.

Sanity is over-rated.

Certainly a waste of $3 though. Before my first multimeter I had a torch bulb in calipers that made testing batteries, switches etc easy.

If I were a coyote, very probably I would. De gustibus non est disputandum.

Coyotes are one of the few members of the canis family that eat carrion, as well as fruits, berries and some vegetables. Roadrunners fit right in.

There are Jackrabbits and other animals that are a lot slower, and
provide more food than a Roadrunner. Not only that, but the Coyote is a
