Found a Sony Trinitron KV-1212

[Kamakiri]

It was in a corner on a sewing table, covered in dust. Price was marked $20, but being half off day, it was down to $10 . Cosmetically aside from the dust on it, it's pretty darn nice!

Now, myself, I don't have any interest in this particular set, but I figured someone here would, especially as I believe it's a 1972 model. So, that said, I saved the set and it's up for grabs here on VK to whoever wants to pay me a Hamilton (that's who's on the $10, right? ), pay for shipping, and give it a new home

Yes, the pics are kinda lousy

You'd know better than I would as I'm not even in the U.S., heh.

Got to wonder what the shipping cost to here would be, it would probably kill.

pm sent of Jon passes on it.

That's fine, and quicker than expected. I'd prefer the less-common remote set anyway as I already have the transmitter.

BTW, NS isn't actually an island. Close, but no cigar.

Here's the set on color bars. Picture tube is strong, but it's got some pretty substantial pincushioning. Not sure if there are anti-pincushion controls inside like there are of some sets of the era, but here it is anyway.....

cool, yea I know that effect, there is an adj pot on the bottom left side (from front) but more likely a cap in the sweep, esp if the pin cush pot does nothing.

There are a few problem caps that I cover in one of my videos on the last one.

I just shipped a 23 lb box to Alberta that cost about $85. This thing would probably be $150 or so, since you're way out on the island there....plus it weighs more....

Very nice save! Are the 72 a pain to work on , or is it later sony sets that are troublesome? I've seen a couple sony in my neck of the wood, but I was always afraid that it would be to much of a pain in the neck to tinker with...so I never grab them.

Not at all, that model has pcbs that use plastic tabs like hinges that let you take out a couple screws and then the board hinges out but is still electrically attached. Makes getting to the bottom of the pcb for easy desoldering of parts.

Good to know that! But I was really saying is : I heard that some sony need OEM parts in order to work, no 3rd part stuff will do and that they are hard to diagnose (over engeneering I guess)

The ones to avoid use the SG613 or SG603 gate controlled switch for
a hoz output, few shops would get near one. They were sold apx
'72-'77. Before that not to bad. After that about as easy as most sets.

ANY Sony that uses a GCS is something to STAY AWAY from!! Unless you are into masochism...I do NOT think a KV-1212 does....but may be wrong. If you have the SLIGHTEST problem with horiz. drive..kiss the GCS good-bye INSTANTLY !!

On the same page.
Sony was a super arrogant company in the 70's. Independant parts
distributors were yet to come. If you called them & managed to get
the right person they treated you like dog doot. The shops that did them kept mum on how to deal with them. They were getting $120 to open one, a LOT of beer & smokes at the time. Most of the arrogance went away in the 80's, the parts dept in KC were great & the tech help became friendly. Of course it helped to be an ASC & true franchised dealer !
Anyhows avoid the bad ones & have a fist full of electrolytics for the good ones. Nuf sed.

In a Sony of that vintage, I replaced the damper diode and the GCS, with ECG replacements. The repair lasted about an hour.
The only parts that would last were genuine Sony replacements.
