My First Vintage TV.....

[krimney]

The unit had one of those little cylinders attached with the cable end on one end and two spade termainals on the other. The UHF strips were attached to the VHF antenna. There is also a UHF tuner terminal. I've got the cable running into my VHS. What now??

I also have a high pitched squeal that is just audible enough to be annoying. It seems to come and go.

It looks like the side panels are plastic so I guess the unit isn't that old.

Here are some pics.

with the back off. Lots of tubes all appear to be Zenith brand.

Can't quite tell from that angle, but it could be the EXACT model I remember from my first years. May have been from 1972, from what family said.

The VCR is working hooked up the the UHF strips. I had to connect them directly to the coaxial cable, the little adaptor doesn't seem to work.

I did some searches and it seems to date to the late 60's , early 70's.

Seems to be a bit of distortion in the pic in the top inch of the screen

[krimney]

Like many of us first saw him??

The high pitch squeal seems to have gone away after a while

[krimney]

All the controls for VH, red , blue , green etc are on the back. I also found a thread that mentioned the 20CC50 chassis is hard to find.

switched the tape off and cable is now running through the VCR

The distortion at the top of the screen also goes away on the cable so it must be the VCR or it's interaction with the TV.

You use a simple antenna distribution box, like RS used to carry under the Archer name. It has a center pair for input 300 ohm twinlead and 4 outputs the same. It is unpowered and usually had a piece of adhesive tape on it to attach it anywhere. All you need now is a 75 to 300 ohm balun to go in and you can run wires from two of the outputs for U and VHF or spend a few dollars more for a splitter instead with 300 ohm outputs. Depends on what you have lying around.

It seems to come and go and can be irritating if the volume isn't turned up loud. I have no TV repair skills(unless they are well hidden) and NO test gear other than a Realistic Multi meter.

If I decided to part with this unit , I know it would be preferable to keep it complete. What are these things worth? Whole or parts??

It's something not being properly filtered from the video stage, that's my guess. Old capacitors and an out-of-spec tube are probably the culprit, but I'm not a TV repairman either. Use the VCR and one of those godawful integrateds (like the one you had on top of it ) with some of those troublesome speakers you pile up until you can figure it out.

If you ever want a SMALL TV (A REAL ONE) I have a National Panasonic AN609D 7" you can figure out. Robust CRT but needs caps and a diode or two in the PS (overvoltage to the heaters). It's an Instant On set so I could NOT let it run warm all the time like that, but it had a great picture and it's bright blue, as Matsushita was so famous for never making a dull set.

Send money, guns and lawyers and we'll smuggle it into Diefendorfer's garage without a further charge. (SP sorry I wish Bush was the other half of Anheuser some daze)..

PS somebody tell me if ~~~THIS~~~ National has anything go to with the Panasonic namesake?

making the squeal. It is there even when the volume is turned all the way down. The high pitched squel is emminating(sp) from within the TV, not from the speaker. The sound from the TV speaker is fine.

Steve....It's not an Integrated, it is a very nice Optonica receiver that is MINT with original manual AND Schematics. Only problem is it sometimes jumps in/out of stereo. Nice sound and a solid 85wpc.

Sandy....I've seen a few 4-6 inch tv's around lately in thrift stores etc. Some look like they also have a radio built in. may have been B+W. I am seeing a fair number of Sony Trinitrons around too, apparently a very good TV. If fixing TVs were easier than fixing audio components I may be inclined to look more for TVs. I think that's whay I've got so many speakers...they are relatively easy to repair or to just repalce a bad component. All I need is a multimeter and I'm good to go.

Take it to the repairman then! It's not supposed to do that, but it doesn't sound fatal to the life of the set. STILL...it's not a good thing to operate it like that. Do that and ENJOY it!

Can you turn the muting off, and what are you using for an antenna? Does it only cut out on one or two signals? How is your antenna oriented in relation to the tall buildings in downtown Calgary?

Do you have a TV amplifier such as a CHANNEL MASTER, JERROLD or I even saw a nice Thomson made RCA once! A nice one with a rating of -22 or better and "90 mi+ urban fringe" VHF antenna should do the trick in your part of Alberta, and you can put it on an A/B swtich or an variable pot if you'd wish. I have 6 sets TV/FM/UHF scanners running at times and right now I wouldn't need cable to get 23 signals on TV alone (7 are digital), including two new in the last three months (!!!KKJB 39 is testing as of this week!!!)

I wish I could go to your place and build you a decent antenna system that doesn't rely on cable TV

I wonder if the squealing you're speaking of is the flyback transformer? Aren't they sometimes known for making a squeally-ringing sound... some more than others? I have '72 Zenith black & white set that makes an more than obvious high-pitch noise... moreso than others. It's done that ever since I got the set several years ago. It does, however, remain constant. I think you mentioned that yours comes and goes.

Seems I recall reading somewhere that shoving a piece of sturdy paper in the middle of the flyback can dampen the squeal. Anyone else hear of this? Am I on the right track here?
