Sams Photofacts published the information for model TV-120U in May of 1968. The "U" suffix set shows UHF knobs, your picture with the "NW" does not. Also, it's black and white, not color.

Thanks for the help.

The seller said it was a color set but I was unsure, but I've no issue with picking up another b&w.

Never seen one in 40 yrs including a year at Sony FS.
The U stands for United States not UHF. I dont remember
NW. It just means where it will work & it passes any rules for that country (s).

Lacking UHF it's probably Canadian.
With the title calling it color, looking at the blurry seller picture of the knob captions I thought I read color and tint, but it makes sense it they are contrast and bright.
If Sony had offered a color set that big in 1968 in North America it would change how I understand their history.

Possibly Canadian? That would make sense, I'm close to the border.

Yeah, if I recall Canada didn't require UHF until some time in the 1970s. I think the delay was just because of how few stations we had compared to the US. My city got our first UHF station in 2006, only 5 years before the digital transition.

I've don't recall seeing NW before, maybe it was only on early sets.

Looking at the ratings plate, it shows 110 volts, 50,60 cycles. We were generally rating sets intended for the US market as 120 volts, 60 cycles.
It was probably for use in Mexico as well! :scratch2:

This is Monochrome. TV prefix on Sony indicates that. Yes, 1968, and a USA Model (U indicates United States).

If so where is the UHF tuner all sets newer than 1964 were mandated to have to be sold in the United States of America?

KentTeffeteller 07-03-2023 09:13 PM

Could maybe have been for VTR monitor use. Those sets didn't usually have UHF tuners fitted, or maybe Canadian sale.

I own at least 4 60s-70s VTR monitors and every one that has a tuner has BOTH UHF and VHF. The mandate applied to monitors that had built in tuners and could function as TVs on their own.

Thanks for that update, been a long time since I saw an old Sony monochrome VTR monitor set.

I wonder if this set uses a tube for the HV rectifier. The first Trinitron color sets used a tube HV rectifier.

Every Sony TVR monitor I remember had one of those big scary
square connectors
Also seen BNC's & SO-259. RCA quite rare on industrial stuff.
Sony even converted a tin can all tube Admiral. They added a board that looked
very hobbyist built. Admiral names were removed. I saw a few at
Sony FS in Westwood Ma. I always wondered why they used a POS
set when they could have used a Zenith hybrid or RCA in line etc.

enuf fer now
