speaking of Heathkit... here you go...



EDIT: I should point out that those hifi components in the front are all transistor -- to quote Heath's own catalog copy:

And then the gothic church seen in the distance is kinda weird for an American-made product.

Lots of Gothic Revival churches, colleges, statehouses, etc. here in northeast U.S

This is a very cool SAE brochure that I've not seen before!

I had an SAE pre-amp way back in the day that had the EQ switches in the center, don't remember the model #. Working in an audio chain that took trad-ins I had the chance to buy lots of different equipment in my time there. Would use it for a while and either sell it on or trade it back in for something else. SAE stuff always looked cool and it measured well in the shop.

Is that a nixie clock, front & center on the SAE brochure? I'm not sure I've ever seen a commercial consumer-focused nixie clock. In my memory as a young kid, the world went from flip clocks straight to 8-segment LEDs.

It's a tuner, so frequency indicator. 102.7 FM.

Is there a colon or a period between the 2 and the 7? If a colon, I'd say time; if a period, I'd say frequency.

Ahem.
This isn't difficullt.
It IS a digital FM tuner. It IS frequency.

In the old days, i.e., somewhat prior to VFD (fluorescent), planar gas discharge, and LED displays, Nixies were one of several go-to options for digit displays. RCA's Numitron was another. There were even cruder variants that used, if memory serves, tungsten filaments shaped into the various digits (i.e., similar to the Nixie, but tungsten instead of neon).

Heck, When I was in grad school, we had an early Swedish LKB (Bromma Instruments) digital fraction collector that used Nixies to display the drop count if one were collecting fractions from a chromatography column by volume (i.e., by counting drops of eluate). We had a newer LKB that had LED displays. Not nearly as cool, though.

McIntosh sells clocks* -- SAE didn't.

Sherwood made the first FM tuner with a digital display: the SEL-300, in 1971.

The first microprocessor digital FM tuner was the Draco/Sherwood Micro CPU-100, which also featured a card "memory" (ca. 1976).

both borrowed images, of course.

Imagine what it would cost if it ticked off seconds, too?!

early digital tuner from HH Scott (Maynard, MA): The 433, in 1972 (give or take)

A 1977 HH Scott brochure I have shows an early digital/programmable tuner (somewhat different than the 433 above) which they date as from 1974, and also an early integrated receiver with digital FM (1976).

"You're listening to 102.7 The Time, bringing you the sound of the minute. That last track was the Rolling Stones' 1964 hit, Time is On My Side. But if you're headed to the late show, you'd better leave now, it's three minutes to the bottom of the hour. Next up, here's some Morris Day to send you on your way..." /Deejay

Point taken.


Time and frequency are intimately intertwined...
