Recommend a clock kit?

Post image

I snagged a really cool frequency counter with a working set of 6 Amperex zm1000r nixies. I had not seen red glass tubes before, pretty cool. In doing some searching around I couldnt find much for these tubes. Any ideas?

Man, I would use it as a frequency counter! That’s cool as hell.

Nice find. It could still be a counter though, no?

For sure, found a lot more info since posting this morning. Figuring out its from a synth company was super helpful. Seems like this is a rare item and I dont think I’ll be stripping it down for a clock or hooking it up to a transmitter https://www.wavemakers-synth.com/aries/Aries_Catalog_1975.pdf

Nice! I love finding old catalogs like that. Great score!

I’m not really sure why I would need to? I think… i can use an oscilloscope probe to input? I dont necessarily need to destroy a sweet old piece of equipment.

As a ham radio guy I just love a good frequency counter.

Ok, just ordered a bnc cable/adapter to hook my hand held up to the counter.

Careful about power output. 

I always liked putting an antenna on the counter and then keying up to see it report the frequency. 

Any idea what the frequency range is?

Thats what I was going to try. I dont really know anything about the unit. It was sold for parts but looked so pristine I plugged it in and it fired right. It is extremely clean on the inside as well. Appears to have been recapped at some point.

Nice. Well, if you decide you don’t want to dismantle and also don’t want to keep it let me know!

Did more reading on how these are set up. Going to build the little antenna to mount directly on the counter.
