Very good video.
I put a NOS 11SP22 in my 1966 Portacolor a few years back.
It is now with me under the Atlantic Ocean.
cheers

the huricane/flood got it?

It got the entire collection save for the records and audio upstairs.
not sure I should even be here. carry on guys


.....AHA

sorry to hear about that...

and the finished product

I'm glad to see it turned out that well. The convergence looks good.
Were you able to get the purity perfect, as well?
P.S., you must be using an inside antenna with your DTV convertor. A lot of breaking up. :boring:

yep was able to get the purity and convergence just fine, I did a rough setup so I need to do again with a cross hatch, as I used an ota pic to setup the convergence. The box was on a simple indoor antenna, I should get it on a DVD to get a better pic. Thanks again!

What was the movie you were watching in the second one?

Columbo was on "matter of honor" I think was the episode.

I loved the totally flat "Anyway, that was a success" comment in the vid. :D

Does the bottom always have the circuit board exposed?

the cabinet back has a bottom part attached. when its completely put back together the bottom PCB is protected by a slotted cover. I have to work on the degauss switch, its not working reliably.

Mine was the same model. Had a lot of trouble setting proper purity and convergence, although , as documented here in pictures someplace, I got it damn close. That was a space-heater in terms of radiated heat but it was quite a reliable GE and made a charming picture. Also ran into a case of the tun whiskers on the AGC potentiometer causing a white raster, Blew it out with 600VDC capacitors

this set is using only one of the convergence dynamic coils, the horz ones. the vert coils are not in (green directly to ground). I will have to get a good cross hatch to do a better job of it. It does have some tunable issues (somewhat tunable, I can't completely correct with fine tuning).

It looks sorta like a delay line issue in the chroma, the chroma seems to be shifted to the right a bit. De tune (fine tuner) and it look better (and the chroma gets weaker but easy to up the color to compensate). If you tune it to near sound bars like most set would be tuned the chroma goes into overload, and the colors tend to separate, the green lagging the most to ther right (separate horizontally that is). I have heard of delay line problems, but I am not sure that would account for the tunable issue, except for if the chroma gain increase in the IF pass band would some how make the delay worse. Also do not under stand why the green would the most effected (shifted the most to the right).

It certainly not a big deal as just detuning gets you almost there. My plan is to sweep the IF and take a look at it, but will not make any adjustments until I get some time with my BK 415 on some other sets.

ok looking a bit closer with the color all the way down, I can see a tunable cost in the luma as well.

If yours has the wood grained cabinet then it is identical to my Portacolor.

yes its the wood grained model. I am currently working on replacing the degauss switch. I think this style of the PC is one of the better looking models. Its nice having all the important controls out in the open, some of the later ones started to hide them (like the vert and brightness). I also like the lit up color and tint controls, helpful when adj in a darkened room.

I like the styling too of them too. Never seen any other sets up close to compare control layouts though. Here is a picture of mine.

Yep, that was a great set...what was the chassis? HB?

Used to use her out on the back porch at nighttime.. the nighbors got a kick out of the fact that it had to warm up

I think mine is the HC.

I think mine is the HC.

I see, yours is the earlier model that uses the screws that are through the top, front.
The one I'm working on now, has the sheet metal bars that hook onto the front rear.
