Found a Little color Sony, and it is OLD.
 

The model number is KV-9000. I.m guessing around 1972, or so. The CRT appears to be good, I get a good Horizontal line, and it is white, and plenty brightness, so of course I turned it to min. brightness and Picture, till i figure out the vertical problem.

And, it is a weird one! I do have just a line, EXCEPT when i change the channel, or mess with the tuninng, or vertical control. THEN, it opens (not fully, but over halfway, )for a second or two.

i hope I have a manual for this little trinitron. I've got a feeling some caps will need changed.

BTW-- This set has instant on! I noticed the filaments of the crt, and they stay lit, after I turn it off!, I don't see an override switch, either(yet).

This was a garbage find, a couple of subdivisions from my house. It is missing a couple of knobs, and has a cracked place at the bottom of the cabinet, wherethe front seperates from the back, but is otherwise in good shape., it even has the antennas attached to the back.

Any idea of worth, or rarity?

last week, I found a 1960 Admiral 19" BW portable, also near my house, which I will talk more about in the BW section

I have one of those sets and I think I have the service manual if you don't. With a set that age I would start by looking for open caps. It has a nice picture when working. It certainly beats anything else that size in the early 70's.

that set has multiple open caps in the vert.
btw the osc. is unique in using an sbs.
if tube is good they look nice.got one on my computer shop workbench.

Do you have a picture of this set...is it a really small set like a 5"? Only sony trinitron I have seen from this era is the 12" or so model.
There were a lot of 70's and early 80's Trinitrons brought in to the recycling days this year, most still working or with only minor problems...and our shop has worked on several 70's and 80's which are still in active use...they seem to have the most longevity among the general public of any brand.

Damn ! I trashed one of those a couple years ago-it was my sister's-'cause the CRT was bad. Perfect cosmetics. They DID have extraordinary pictures...I think it was one of the sets the Trinitron "legend" was built on. And yeah, 1972 seems about right-think my sister got it Christmas '72-Sandy G.

I -think- that it's this one: eBay Item number 5746542831

My memory of this set was that it was more of a showpiece than an hot seller. Price was astronomical.

far too new.
they have mech tuners and are tall .
uhf on side

OK I think I remember which one you are thinking of now...I found one for $1.00 at a junk shop in Albany, Ohio...cleaned the tuner and my parents are still using it in their bedroom.

My Dad bought a new Trinitron about '71 or '72. IIRC the model number was KV-1701 and I can still visualize it down to the smallest detail. It too had the instant on and there was a switch on the back to turn this on or off. The picture was outstanding and seemed sharper than the majority of the competition, but lookng back I suspect that part of the reason he bought it was all the hype surrounding the Trinitrons at that time....plus the reknowned Sony quality (at that time anyway).

Price was around $300 and we got it a discount place in Brooklyn called JGE "What's the stooorrrrryyy Jerry?" Who knows about that? HUGE ad campaign back then in the NYC area.

Need an audio IF chip for one of these
 

Anyone got a spare they can manage? I think it's an M1548(? don't have number handy) and is about a 16-pin DIP that handles the IF demod. Part has been NLA for quite some time. I've got one that has a good picture but no audio due to this chip being bad. It lives in a shielded can on the board to the left of the CRT when you look at the front. Model KV-9000(U) was what encouraged large adoption of Sony in the US. VHF tuner on the front and a side-mounted continuous UHF. Picture is outstanding for a small set, especially when it was new.

Now you tell me!
 

Pretty sure I threw one away before I knew you or what to do, sometime in 2003 :no: :no: :no:

KV-9000U. That's the one. UHF knob on the side. My sister had it from '72 til 2001 or so when the CRT started to die, as I said. Think it might have taken a lightning hit summer 2001, the same one that got my Yammy, B&O TT, JRC NRD-535D shortwave set & other stuff. Shit, we ended up having to re-wire the house...-Sandy G.

Yeah, it has the uhf knob on the side.
 

And I think it is a 9" screen, I do not think it is 12". IIRC, Sony model #'s are indicative of screen size.

KV-1756= KV model 56, 17 inch
KV-1923= KV model 23, 19 inch

later models use nomenclature like this:

KV-19TS20 KV model TS20, 19 inch and that one is a 1991 set with the "new" version Trinitron CRT I would believe but don't quote me...

I don't know how they tag the new models, perhaps I don't care anymore...

Well, THAT'S a helluva attitude!!! <grin>-Sandy G.
