Sony kv-1710
Picked one up tonight, has a nice sharp picture and good sound. I checked the crt on my B&K and the red gun is a little weak, color tracking isn't great, however it checks perfect at 8.8V. I tried to let it sit at 8.8V for five minutes and all three guns were even there, but back to 6.3 red is still low. Oh well! I have always liked this era of Sony... Looks mid 70s

On mine the blue and green are both about the same - red on the other hand is quite a bit lower, at the top of the middle area between good and bad... Not altogether bad, but bad enough to screw up colour tracking. The TV is totally watchable though. On the up side, learning how to use my B&K got me all enthusiastic and I tested the 25XP22 on my RCA CTC38... Tested near the top of the range on all three guns and colour tracking almost ideal... Wasn't expecting a TV from 1969 to test so well!
Should I attempt to rejuvenate the red gun? I have $20 into the TV and I wouldn't say I need it, but I am hesitant to ruin it

Hmm maybe I will leave well enough alone. How does one go about setting grey scale on a sony? This one hasn't been touched since factory, and a touch up wouldn't hurt with the weak red gun and all. I am not seeing a normal/service Switch anywhere.

I would not go beyond the " clean & balance" setting if you
rejuve. Sony jugs just dont take it. Most the time in a few days they look like dog doot again. You can also H-K short it. As far as grey scale goes make note of where the pots are set then tweak things, there is no service switch. Do it in a low light room & dont expect to drive the set balls out.

No service switch? I am starting to see why techs don't favour sony. It is interesting to compare this tv to my 1973 vintage zenith portable hybrid TV, if I am to imagine myself buying one in the store I would probably have held out for the Sony, but the zenith is sure easier to work on.

Thing were done a bit different by Sony and we were not used to solid state yet. Parts were also a problem, and Sony's arrogance. Had you got the Sony back then would have cost you $100 more than the Zenith, a lot of $$ back then. 73 Zeno
