The Zenith Radionic Cobra cartridge was great when it came out in the late 1940s. It had good compliance and relatively low record wear. Zenith dropped the cartridge in the mid-1950s and the later ceramic Cobra cartridges have better frequency response for hi-fi. Wurlitzer used the Radionic cartridg...

The Zenith "Twin 7" record changer is indeed a rare bird.

Columbia did push seven-inch styrene 33s for a time, but RCA's 45 format was simply better for singles. Better in both sound quality, and durability.

That's the best way, and power tools should be not allowed anywhere near the plug.

Always wipe the plug and pan clean with a rag.
Preferably, always use a new washer.
Always start the plug with your fingers, and do not over tighten it.

I''ve run many cars over 200,000 miles, and have never had a drain plug 'wear out'.

That set looks about 10 years older than the 1971 date on the receipt.

Edison discs are vertical-cut (up and down, not lateral like 78s). The used jeweled styli, not steel needles. Playing them on a 78 player will do damage. You can only play them on an Edison player, with a lead screw to move the arm along and a reproducer that responds to vertical modulation. Chris ...

Edison Diamond Discs have a much more natural sound than acoustically recorded Victor / Columbia / Brunswick records. You can especially notice the difference on the sound of the piano.

Restore-a-Finish is deigned to melt the old finish so it can fill in the scratches.

Restore-a-Finish will not work on modern poly finishes.

My grandfather had a 1961 Bel Air 4-door sedan, 6 cylinder / Powerglide. It was very trouble free and stayed in the family into the late 1970s.

I remember how wide and spacious the floors were. Now I understand that is because of the notorious X-frame design.

In case it helps, I found these:

While I have no interest in buying a "Wheel 2", I do enjoy Techmoan's Youtube channel. He does a lot of videos on odd obsolete music formats and interesting equipment.

Some of these Bell & Howell consoles were rebadged as Columbia.

GE's consumer electronics division has been gone since 1987 when they sold it to Thompson in France. GE has been going downhill ever since Jack Welch ripped the soul out of it.

I use this one when I need a contact cleaner.

Deoxit D5 is great for switch contacts. For potentiometers, Deoxit F5 is the correct product to use.

That sign was hanging over the VTRs in the AV department at my high school back in the 1970s. I got a big kick out of it.

That was for slightly newer sets that used the E-V 132 cartridge.

The record changer is a Webster-Chicago model 100 3-speed record changer.

I've never seen that tape deck before.

I give Chrysler credit for continuing to build hardtops after the other makes dropped them.

I always thought the spec for the EV-26 was 5 grams, but this original ad from 1958 says 6 grams --

Might be worth a try to compare voltage readings between the two channels.
