OK, I'm ready to do an alignment. I want to do the Video IF and Sound alignments. Any words of wisdom?

Thanks.

If you have a crystal stabilized rig you can run through video first, then go through audio and make sure it matches up channel for channel. If you don't have crystal stability it doesn't much matter, since you'll likely wind up doing both multiple times till they get close.

OK, here is where I am on the alignment.

The video IF response curve is a bit peaked but I'm getting a great picture.
The audio curves look real good too.

When I'm playing a DVD the picture and sound are great.

When I'm OTA using my converter, the picture is great but the sound is pretty muffled. When I change channel 3 or 2 I get real good strong audio from the local FM stations.

I can't play OTA using channel because there is too much interference with the FM stations.

I tried adjusting the slug for channel 4 and the audio improved but there is still a marked difference between a DVD and OTA audio.

Any suggestions as to where to look? Does the tuner frequencies need tuning on channel 3 and 4?

Thanks.

Well, it looks like my converter is bad. I tried my other converter and had great sound! Too bad the picture quality isn't as good as the one with bad audio.

The good thing is that the TV is playing very well.

Don't those digital converter box thingies have separate composite video and audio outputs that can be run into a high quality agile modulator? I'm assuming the internal modulator is the weak link. Believe it or not I've never dealt with one of those converter boxes as we haven't had any broadcast TV signal entering our home since a few years back when we cut the local cable company off.

Kevin,
Yes, they do have some separate outputs. I'll give those a try.

I finished making the masters for the labels on the back of the chassis. Now I need to get some of the grey/silvery paper and some off white paper for the "Caution" label. Then run them through my laser printer and then glue them on the chassis. Pictures to follow when I have them printed out.

Here are the labels on the back of the chassis. What do you think?

Very professional. Wanna make a set for my 8TS30?

The labels looked great, but they were the wrong color. I went looking for a better match tonight. I didn't find one at least for the adjustment pots. Those labels are a lighter color than the big model and serial number label. I bought some sign vinyl at Michaels and ran it through my Brother laser printer. The labels turned out great! Again the pots labels are a little too dark, but the model/serial number label looks great!
Tomorrow I'll visit some sign shops to see if I can come up with a closer match for the pots and UL labels.
This stuff is called Oracal and is 3mil thick and has a very good adhesive back to it.

Here is an overall view of the back:

Once I get the right color for the pots, I'll give full details and make my files available to anyone that needs them. More details to come.

That looks rather... Excellent! I like that you were able to duplicate the fonts for the various information on this label. And, the Logo etc. is perfect.

Bravo! Thanks for sharing.

[Crist Rigott]

Thanks! The labels are very good indeed. Not a perfect match, but pretty close.

I had to order some material today so it'll be a few days till I get the new material and then see if it's a better color. So it'll be about a week till we know. Stay tuned.

Very impressive work. It's so great seeing how a classic set like this looked when it left the factory.
