1970's Sony trinitron worth it ?
 

Theres a listing for 1 of these Old Sony Trinitrons for $20.
Anyone know the year or model ?
Worth getting ?

Screen size looks to be under 19" so it wouldn't be of much interest to me, but I would have to say yes in your case. Mid 70s maybe? I love my '87.

hmm. similiar

Worth $20? maybe, $250 no way.

Late '70's. Probably worth $20 IF the CRT is strong. I'd turn it on before purchase to see what the picture looks like. I've seen many weak Sony CRT's from the late '70's-early '80's and Trinitron's usually don't rejuvenate well. Several years ago, I junked two early '80's 19" Sony's that had a great green gun; but, the blue and red guns were totally dead and wouldn't take a hit. Most of the Sony's that would take a rejuvenation looked good for a short period and then fell back down, looking worse than they did to begin with.

I saw a portable one of these at the local thrift a few years back for $5.. I didn't get it.. I went back for it, and it was gone.. These 70s and early 80s Trinitrons seem to be hot items.. I'd get it, if the CRT is good..

Looks to be a KV-1951, 1976 model. has a great picture of the CRT is strong. I just had to toss one out, long story.
Great companion to an SL-5400 Betamax :)

Worth about $25 if the CRT is strong.

76-78 my guess. If the set is totally dead dont touch it.
Probably has SG613 & you will never get it to go.

73 Zeno:smoke:

Maybe a KV-1521 or KV-1721? Those (and the remote control versions) were the best sets of their sizes in the late 1970s and early 1980s.

Those Hor out "transistors" and the 2SC867 LV regulator HAD to be replaced with Sony OEM parts.
I could never use an SK, NTE, ECG, HEP or other replacement tho they were listed as subs

RadioTVNut nails it on the CRTs, once they go weak there is no coming back

I made that mistake! the set ran about three hours.
I used to get my Sony parts from Joseph Electronics in Niles, Il. :yes:

Reminds me of my KV-1205 from 1978. Which is a low hours set with a very healthy CRT but needed chassis work due to intermittent start-up. Luckily, all it involved was replacing some leaky lytics. It's true; the crt's don't rejuv well & the semiconductors can be confusing and unobtainable.

Joseph Electronics In Niles Illinois are they still over there . I thought they went out of business . Just asking . I use to live in Illinois but cant recall if they moved .

IIRC, the last time I was there was in the mid-80's. They're probably gone by now.
I quit repairing TV's, on a regular basis by the later 80's, so lost track. :sigh:
