Maybe the easiest fix would be to add another S on top of the current coat, rather than trying to get back down to the level of the original decal. Most likely would not be noticeable. And even if the most highly trained eye might be able to figure out what happened, we won't tell anyone to look. :)

Oh, I like that idea! I'll try that tomorrow.

Over the past several days I wet sanded down the cabinet with 600 grit. This sanding got the cabinet real smooth with just a spot here or there of the grain needing some extra lacquer to fill it in. But over-all it was very smooth.

Tonight the weather cooperated and I shot a couple of coats where the decals go. I replaced both decals on the left side of the cabinet.

Then later on tonight, I shot about 10 coats of lacquer on the decals. That will dry till Sunday when the humidity will be low enough and I might be able to put on the final coats,

OK, here is where I am.

I wet sanded the cabinet using 600 wet/dry to level the surface.

I did darken the hatch ever so slightly with a very light coating, dusting? using my Mohawk Brown Mahogany toner.

Then yesterday I shot about 6 to 8 coats more of clear.

Today I'm wet sanding it again with 600 grit to again level the surface in preparation of the final clear coats. Maybe tomorrow.

I am really looking forward to seeing it finished. You'll have one of the finest examples in existence.

Just a quick update.
I did some traveling lately and attended the ETF Convention. I'm back home now and will resume on the 621TS cabinet this week.

Well, this is going to be a long road. There were 2 small areas that needed a little help before the final top coats. The repairs didn't go so good, so I stripped the front and top and I am starting over on those surfaces. The sides are fine.

Tonight I applied several coats of sealer on the sanded veneer, let that dry. Sanded with some 600 very lightly and applied the grain filler.

In a couple of days I'll sand that off...etc.

Gotta do it right!

Here's an update.
The above refinish didn't go well enough for me. So stripped it again and refinished it. this time I'm pleased with the outcome. My previous attempts at grain filling didn't go so well. I learned that I was sanding the grain filler too much and ended up with little grain being filled. The last time I didn't sand so much and the grain was nicely filled for the clear top coats.

I used gloss clear and then the semi-gloss for the final 5 coats.

I'll start sanding with some 1200 that I have and move on with 1500 and finally with 2000. then rub out, polish and wax.

Looking great! Here's an honest question, however: People love to do the hand rubbed polish, because it looks fantastic, but it isn't really true to what the set had originally. What you have now is pretty close to original appearance. So my question is -- is it better to make it spectacular and polished, or better to make it look original?

Obviously this is just a matter of personal preference, so there is no right or wrong here.

And if you're going to hand rub, why the semi gloss (which includes light diffusing filler particles, which also slightly roughen the surface)?

I like as-prayed final coat, since I believe that is what most sets really had, but I also admit that hand rubbed finishes are pretty cool to look at.

In reality, I see almost no modern refinishing attempts that look like the original. Modern lacquers aren't the same as what they used to use, and hand-rubbed is over the top. Has anyone really perfected recreating the original appearance for these things?

OEMs probably spent all of five minutes on finishing cabinets and they still look better than 90% of the home brew stuff I see and what I can do myself (Crist's is an obvious exception).

My 621 has it's original finish in pretty good shape and it's rather glossy, I have also seen other sets with good OEM finish and they were glossy, I don't think the modern idea that old stuff was somewhat dull and resembled a 0000 Steel Wool rubout is correct, or at least not always correct.

I have not done a cabinet for years and never one to this extent. But i will say that I do like the looks of a rub down with 0000 steel wool too.

Very nice job indeed!

I started to sand the finish with some well used 800 grit then switched to 1200 grit. Next up 1500 grit then followed by 2000 grit.

I'm cleaning up the knobs and such and I'm going to put out a call to see if anybody has a channel selector escutcheon. Mine is plastic and it was cracked when I bought the TV. I'll list it in the classifieds too. Thanks.

You need the real brass one for your set. Someone obviously swapped it out for the later plastic type. They were used for quite a few very common sets including the 630TS, so they shouldn't be too difficult to find.

Don't think I've ever seen a better one. Even your pictures are well done.

Breath-taking! You've made an absolute jewel out of set that already is a beautiful design. I too would definitely say it's the most impressive 621TS in existence.
