1950 Mercury TV Console Model 0800 106 Restoration - Videokarma.org TV - Video

I have never shared my builds, but I decided to make a post about this
TV as I have a fair bit of pictures on it and figured I would share if
others were interested. First off, I am just a hobbyist and am
learning as I go. I have restored a bunch of tube radios and a handful
of tube TVs so I still have a lot of learning and mistakes left to do.

To start off I found this TV on my local Craiglist for $50 about 5
miles from my house so I picked it up. It has the original back which
is nice, and after a warmup, the picture tube checked out so I decided
to go forward with the restoration.

The cabinet is in nice shape with interesting original handles. No
veneer damage other than a couple of scratches. The worst part is the
top has some alligatoring to the varnish.

I pulled the turntable out and the interesting part is this TV even though being a 1950 the record player has 33, 45, and 78.

The power cord was rotten, two of the belts were shot, the motor was frozen, and the crystal cartridge was dead.

I replaced the power cord. I took the motor apart and lubed it up and got it working nice and smooth. Cleaned and lubed all the gears and changer parts. Cleaned off all the old goo left from the old belts and got everything spinning freely again. Idler wheel so far seems really good. As for the crystal cartridge, I put in a Pfanstiehl P-51-2 for the time being. Finally, I cleaned the wood and polished the bakelite.

The belts, on the other hand, have turned into a real hassle as they are a very odd size. I hopefully have some on the way right now.

I then started on the radio chassis. This TV console has been really difficult to get any service information on it. So far I have only found one page in Riders volume 5 with a schematic for the TV chassis, nothing for anything else.

The radios dial cord was broken. Luckily the cord routing was pretty simple and the broke cord was still hanging in the original location so I took notes and lots of pictures and restrung it. There were only a few caps on this chassis that I changed along with a couple of resistors that had gone up in value slightly. I finished with a new lightbulb.

Next, I started on the TV chassis. This TV has seen a lot of service work over the years. The CRT is a rebuild, the flyback is a replacement, and there are a few capacitors and electrolytics that were changed. Also, all the tubes were of different brands. So this TV saw a fair amount of use, but no one has been in here to work on it for around 50 years.

I replaced all the capacitors, electrolytics, power resistors, few resistors, and power cord.

I know some people like to restuff the old paper caps, so I did save all the stuff I took off the chassis in case I decide to go back and do that. Right now I am just trying to get it up and running.

The first power-up was a bit confusing. I did not get any high voltage and when I was checking my voltages on the board they were coming and going. It was happening so much I started to doubt my meter or probes. I ended up finding a broken wire coming right off the power transformer for the main B+. It was making contact but it was broken so it was just laying on top of the terminal. I fixed that and all my voltages went right to where they were supposed to be and I got a raster.

I cleaned the tuner and I hooked up a DTV box to it and was able to get a good picture. However in the high voltage cage I am getting some corona around the socket of the 1x2 if I blow on it. I have ordered some corona dope and am cleaning the connections and reflowing the solder.

So this brings me up to current progress as of today 12/13/19. I have been working on this for around a week and a half. I would have got more done but I keep having to wait on parts to arrive.

I am not sure if people are interested, but I can try and start uploading my restoration projects as this time of year I tend to do lots of them.

I hope everyone has a great weekend!
Chris.

Marlon Brando playing records on the same model Mercury TV.

Did you buy this set near Los Angeles by chance?

Very interesting cabinet configuration for a combo set. Like, the tv is on the left 2/3 but so is the turn table. Nice looking thing though.

WOW!! That is cool!! So I bought the TV in Sacramento and the guy I bought it from it was his Grandfathers TV and he was a stuntman in Hollywood Westerns.

Thanks! I had never seen one before, it is an all-around odd TV but its really grown on me. The doors have kept the original safety glass and grill cloth nice.

Also here is a picture of what is on the CRT.

I like that "Mercury" name on the set. It makes it unique. It's a good looking console too and great with the pic of Brando watching one.

Thank you! If I understand it correctly that Mercury is the record company, and for a brief time in 1949-1950 they tried to get into making TVs. They made only a couple of models and this one seems to be one rarer models as I have only been able to find one more example of it online. Now someone might correct me on that.

Also, I really love that Marlon Brando that Eric H showed me. I think I am going to print that, frame it and set it on top of the TV.

You're welcome and it sounds like a great idea with the photo. Yes, there was Mercury records in the late '40's through the '60's. Mercury was a popular name.
"Unique" is always what you want with an early TV and your is just that. I can't wait to see it completely restored. Good luck.

Thank you. I am excited to get this working, I really was unsure when I started if this set was going to come back to life because it had been sitting for so long and the CRT tested very weak. I had basically no emissions even after letting it run on the tester for 2 hours. I resoldered the pins to be sure. After that, I ended up using my SuperMack on the restore function and gave it one pass. The emission shot right back up, I had cut off, and even the lift test was strong. Now that the TV is running the picture tube seems great.

Today I got my Super Corona Dope and I have been working in the HV cage trying to fix my ozone problem. I have found some spiky soldering on the pins I fixed, I coated everything in the corona dope, and I changed the 1x2 as I am thinking it might have a hairline crack. I also noticed I was just starting to get a little high voltage leaking from the tire of the flyback if I blew on it. I painted the tire on the flyback with corona dope and that fixed it. The tire itself looks fine, no cracks or anything. Still appears if I blow air I am getting a little corona around the socket of the 1x2 where the tube goes in, it is almost like its forming between the pins on the tube side.

Today I worked on fixing the internal antenna. I had a few great ideas from people here. I ended up using Elmer's glue and gluing the foil back to cardboard. I was missing a couple of pieces but after a look around the cabinet I ended up finding them. When I was done I hooked up my meter and I am getting continuity through it, how good of antenna it will make however I really don't know. But at least it looks better.
