Nice stuff. I am drooling over the Teac 4 channel RR. It would look fantastic next to my Marantz 4400 quad receiver.

Marantz always made cool stuff, love the oscilloscope displays they used The Technics SA-800 receiver I have has a jack supposedly for and add on to do quad but I don't thing it ever was made. I hoping to pick up one of the earlier quad units they made like the SA-8500X. I do have a Pioneer QX4000 quad receiver someone gave me that I still have to go through.

Ooh, silver face Technics with FL meters.

NICE.

What exactly does the "flash o graph" tube do?

While I was searching for an online pic of my old freq counter, I came across what looks like modern builds of these-

Nixie tube spectrum analyzer.

Nixie tubes are definitely old school, never seen any like that spectrum analyzer. I still have an old HP frequency counter with them. I'm addicted to the Technics stuff, got a couple of their cassette decks with the silver fronts with the florescent displays. That amp is the only one I have with that kind of display, the other silver face units I have all used the LEDs for the power meters

I suspect the flash o graph is signal strength indicator (a TRF radio amplifies the AM and then a diode detect for sound, and possible signal strength).

This is probably the flash o graph tube:

I just passed up a 25WPC silver face Technics with a silky ball bearing, flywheel analog tuner.

It was $25 at my favorite honey hole thrift store.

I simply don't have room for a low power 5th receiver.

Too bad, it was nice and that was 25 real WPC.

I'd be willing to bet it was donated with a pair of Yamaha Natural Sound 6.5 inch speakers of the same era they put out a few weeks before. that would have been a great setup.


I used to have a SA GX-500 80 WPC with that neat parametric EQ with graphic display.

At $25 I probably would have bought it, Lord knows I don't need anymore stuff but something about older Technics gear I cant resist. I love the flywheel tuner on my SA-800 receiver, I bought it when I was 17 years old and its worth more now then when I bought it. Seems all the " monster" receivers from the 60's and 70's are very collectable. The GX-500 is a nice example of early surround sound home theater units. I work for a company that provides the television trucks for most of the live sports and entertainment award shows you see on TV (before the pandemic) and every couple of years the trucks are upgraded with the newest equipment, unfortunately this has fed my addiction. As some of the old analog audio gear come off the trucks for scrapping if I find something cool I bring them home. Sound processors, tuners, CD players, tape decks, speakers and even an occasional mixing board. With the tuners it led to having to find a matching amplifiers to go with them on eBay. Not sure if I'm a "collector" or "completest", I do the same thing with Post-War Lionel trains so its probably a mental issue. I'm grabbing pictures form the internet since my stuff is packed away but a couple of the treasures I saved from the company E- waste bin

Nice.

Bottom right looks like a mate for my GX-500.

I kind of miss that one.

Does anybody like or have any mono "hi-fi" equipment? Here is my Sherwood pair. S-3000 tuner with S-1000 amp. The amp has tubes installed horizontally to keep the height of the case low. It produces 20 watts. The tuner has an eye tube for precise tuning. It also has an output for an accessory to receive stereo broadcasts. They are sitting on an Allied Radio model 3001 speaker.

I have a 70's Sherwood 9910 on the back burner.
