Nice find and should be a good performer. That one looks like it was built by Toshiba for Magnavox.

Interesting that it doesn't say "No user serviceable parts inside."

That is the giveaway that it probably has compactron tubes in it. That is a great looking set, probably early Seventies.

Oh, I had thought it was an SS set. :/ :p

My second clue should have been the 1.1 amp draw.

It's a tube set ??
Anyone know the year ?
How does the front plastic screen cover come off ?
I want to polish it.

This one will surely be a tube set.

Magnavox made some hybrid 9"/12" sets that had a horizontal output/damper tube, a horizontal oscillator tube, and a vertical output tube. The rest of the set, including the HV rectifier, was solid state with the sound and IF circuits on plug-in modules. I think your set may be a little older and has more tubes; but, I could be wrong. The hybrid set I'm thinking of was, I believe, a true Magnavox and one of their last tube models.

In the early Seventies, tinted plastic sun shades were a popular feature on many portable TVs. Most were just a press fit over the screen with no clips or other retaining mechanisms. Check around the cover. There may be an indentation or other finger hole to remove the cover. Don't force anything and don't use any kind of pry tool to remove it. It should come off with relative ease. I never liked those covers. They dim the picture and are often easily scratched. I had a little 9" Panasonic that had one. I never used the cover. I polished it up real good and put it away. I only put it back on when I sold the set.

I just noticed in your ninth picture from the top there is a really good view of the finger hole for removing the sun shade. It is in the lower right corner of the screen on your set.

I'm going to guess '72-'73.

Yes there is a little indentation on the bottom right.

Just FYI: There were some of these little 9" sets made where the sunshade was permanently attached. I remember a G.E. 9" in particular (circa 1970.)

USUALLY the screen is held on by 4 claws. Just needs a little
pry on them & it pops out. Look for them near the corners,
there are usually 2 small cuts in the screen. Sometimes they just
push in place & are held by the tight fit. A few are pernament
so pry carefully !
As said on the other list I am 99% sure its a Sharp set.

How does it pop back in ?:scratch2:

Just snaps back in. If you have ever taken apart a flat
monitor they use claws but much more aggressive ones.
Hard to put into words, maybe someone can put a pix up.

Thanks.

Just turned the TV on tonight. The tubes inside are really bright and get hot !
Works like a charm, but the VHF channel knob is worn inside the plastic, so it doesnt change channels good. Keeps turning.
Anyone got a spare ?

With a 1.1 amp draw? Think of what you could save on heating bills!

Seriously though, better leave it off until someone with more knowledge on this can chime in, before any damage is done.

What damage can occur ?
I mean it's lasted over 40 years now... ! :yes:

Oh, I was just guessing that tubes aren't supposed to run that hot, considering that you seemed surprised about it. Maybe it's been sitting for a long time and something went out of whack during that time?

All things considered, very nice portable.

Im probably gonna take it in to a shop and get the switches cleaned an try and repair the channel changer knob..

Take the cover off and see how many tubes are in it. The more tubes, the more heat will be produced!
If there is only a few tubes, it is a strong possibility, it has a diode heater voltage drop. It should be noted on the tube location diagram. If the diode is shorted, the tubes will receive full line voltage. :sigh:

I went to my local TV repair shop that has been in business since 1969 and they had and original extra VHF knob for it.
The one that was on the magnavox was worn inside and was just spinning. Total fluke !
