Beauty of old electrical and measuring things, etc.

Some things I want saved for the for the future are geranium diodes and mylar variable capacitors, a small verity of tubes, old tube televisions in prestine condition, old solid state black and white televisions with air gap tuning variable capasitors in clean working condition, a few 1960s table top radios with the old style carbon comp resistors and ferite antennas, XT computers with 5-1/4 fdds, the works on that one, Mac se30's that still work with software, and dip IC's. Oh and quality VOMs.

I hope somebody keeps a warehouse full of this stuff.

Edit: don't forget the old tape decks and VCRs.

The geranium joke reminded of the time a woman came into the store looking for self abasive tape, you know the kind that’s sticky on both sides.

And don't forget to empty the grid leak drip pans...

I'm doing a pump-down with my "new" old Welch 1402 vacuum pump. It's doing a beautiful job.

Will there be any dark matter inside the old vacuum? :-)

It looks good up in the air.

I thought it would look neat to add some navigation lights to the Narco navigation antenna installation.

Aircraft navigation lights are placed in a way similar to that of marine vessels, with a red navigation light located on the left wingtip leading edge and a green light on the right wingtip leading edge.

Is that a VOR or RDF ? Does it find your local radio stations ?

VOR 108.1 to 117.95 MHz and communications 118 to 135 MHz. The VOR station that it's pointed toward is the Butler, MO VORTAC station @115.90 MHz.

Here's some of my RF stuff:
RF Stuff.jpg


I came across this Kris 23+ CB Transceiver a year or so ago. It's in pristine condition and was in it's original box. I haven't found the exact time these were manufactured, but they were made in Japan. Probably in the late 1960s or early 1970s. Definitely beautiful; condition and all.

Now this Hammarlund CB-23 is what I used back in the 1960s. They were advertised in the June 1963 edition of Popular Electronics. Very hard to find now days.

Here's a transmitter for the 20, 40, and 80 meter Ham bands. It will require lots of work should I ever get to it.

Amazing condition on your memorabilia, Don !

I have a Heath DX100 someplace i think.

What a time we live in.. My grandmother lived from times of horse and buggy to moon landings... We've lived from vacuum tubes to cellphones and internet.. It's as profound as the printing press...

It's really amazing to think how short of time this has occurred. I wonder what the world will be like after a similar amount of time.

I probably shouldn't post this photo here since it's not beautiful in it's current state. It had a hung-up vain blade, I think. It's going to be another late night.

It should look like this.

Beauty of hardware doesn't just come from it's appearance but also it's functionality.

A neighbor of mine brought me a bucket with ~75 old vacuum tubes. So I put them into my tube caddy:

But what I found interesting in the bucket was this 4-pin vibrator with the original sales receipt. Back in the day it cost $1.79:

Vibrators were used a lot in old car radios to make "a.c." by chopping the d.c. supply voltage:
