The built-in UHF antenna and tuner are working better than I expected and I can pickup LP channel 48.

Very cool to watch TV the old fashioned way without firing up a transmitter.

Great job man! That cabinet turned out beautiful. I can't even tell the top was redone, the color matches perfect. Nice picture too, I wish there were some LP stations closer to me. I can pick them up, but not clearly.

Looks like a borderline weak H oscillator tube. The pic should come on fully locked in.
Not sure how out-of-sync horz sweep would cause the arcing sound, though.

Does this tv have a piece of metal from the chassis that lays on the dag of the CRT to bleed off a charge? Is it workin okay???

SR

[bandersen]

There is a metal tab at the top and bottom of the CRT tension band than press against the dag. I'll double check. I'm also going to check the tubes on the sweep board again. It does take a while for the set to lock when turned on.

I'm a little distracted by a free set that was just dropped off Details to follow.

Even if the osc. tube tests 'good', try dropping the heater voltage a notch or two. Or use the 'life' test if the tester has it. If emission drops abruptly the tube is borderline in oscillator service.

In instances like this, the set itself can be the best tube tester.

I'm wondering if the Horizontal osc coil needs touching up? The one on the board I mean, not the Consumer used control.
You may just be hearing the screech of a tortured oscillator trying to start up.

[bandersen]

Perhaps. I'll pull the chassis out once the cabinet refinishing is done and go trough all the factory adjustments.

I spent a lot of time and used a lot of tape to get the set masked off so I could spray the top. Lacquer dries after a couple feet in the air so I'm not concerned about any getting on the feet on my floor. They will just be some brown dust I'll clean up with a swiffer.


Here it is after three passes with the toner and a couple coats of semi-gloss lacquer.

LOL - The top isn't done - it just looks good in the dim lighting.

The weather is finally warm again and I should have the top done soon. Meanwhile, I snapped the neck off the original, dead CRT so I could dispose of it.

I wish I could just reach in there and fix the filament

[bandersen]

I finally decided I was happy with the top and removed the masking tape. It's not exact but a pretty decent color match I think. I'd have to do a custom blend to get any closer. After it cures a while longer, I'll knock it down with some steel wool and pumice.

Now I can get back at the electronics inside

You could fix it now...Though it probably would not do you any good without CRT rebuilding equipment.

I tend to keep electron guns whenever I have to snap one off. I like the way they look...Especially the delta-guns off of rectangular color tubes; those sort of look like Lightsabers

[Charlie]

Man, I think it came out really cool! It certainly looks like it was well worth your time and effort!

Hi All;
Bob, I am Glad to see that it was you who snapped off the neck, instead of something Your picture tube checker did to it..
THANK YOU Marty

Why would you think a CRT tester could snap off the neck of a CRT.

CRT testers are electrical devices that attach to the CRT base via a wire and socket and apply fairly low voltages. The only way someone could snap a neck off a CRT during testing is by having an unsafe procedure or an accident. The only way a tester could neck a tube when used properly is if the tester got hit by lightning during the test(CRTs have been known to have neck failures and implosions if subjected to voltages more than 50% over their specked HV anode voltage).

[bandersen]

A more likely scenario would be brushing against the set when the back is off. That stubby little necks sticks out just enough to easily get broken.

I'm happy to say that I have yet to break a CRT except on purpose. Uh-oh! I probably just jinxed myself

Thanks! I hope just a little more tinkering and it'll be done
