Here's one thread about the Portacolors:

There are surely others. Try using the search feature on the site, it's wunnerful (said in a Dinah Shore voice)

I just love this forum! It's like hot rodding a car what with you guys coming up with improvements like this!

You said "irreversible" which I appreciate, that's my philosophy when I modify a car (unless it's a full bore custom job). Like adding disc brakes or electronic ignition to a old heap, it's great to upgrade without it being readily noticeable (except from a performance point).

Andy,
I see money possibilities here. Maybe you could get in touch with the real GE and see about bringing back the portacolor. Portacolor III or something like that. Price em at about $99 or so. Volume discounts available if you buy them in quantity. The advertising tag line could be something like "The picture that beat Zenith and RCA"! Imagine the possibilities- tee hee.

Simply great, Andy! Thanks for sharing those tips!

Just a couple of weeks ago, I was actually wondering how easy it might be to add DC restoration (probably using a single diode) to a Portacolor set..! [To me, the lack of DC restoration just gets visually annoying after a while, plus I thought it might be amusing to built a retro-looking cabinet for a cheap DVD player specifically to attach to my PortaColors and other sets from that general era. :-) ]

Now you just need to add automatic chroma gain...

I'm running a bit behind in updating that page, but, eh.

My dad actually works for GE. I'll run it by him next time I talk to him, lol.

Hate to say it, but all they'd do is slap a "PortaColor" label on something made in China......

In that case they'll need to change the spelling to:

"PortaPotty"

Andy,

Unfortunately, my Portacolor with the clock/sleep-timer is currently in storage, but here's about the best view I can come up with of the clock knobs with the pictures I already have of that set.

The clock knobs are made of thin, flimsy plastic-- it's no wonder that yours are missing! Both of the clock knobs on mine are cracked and have bits missing from them, but they seem to be pretty much just simple knurled plastic cylinder-shapes; nothing fancy about them.

If you really need a better image, let me know, and I'll dig it up from storage and take some new pictures for you.

Sorry to dig up the old thread, but could you re-post the schematic for the DC restoration circuit you made, Andy?

Ditto! I ended up getting two Portacolors after this was originally posted and by the time i went looking for this thread the scans were gone.

Thanks alot Andy. Eric is giving me a portacolor and I want to experiment with it a bit.
