I'd like to have one of those if I had room.

Wonder if you could put a modern HD Light Engine inside one of those, not that I would but it'd be pretty wild if you could, tell people it's original 1949 color. :D

BTW if you have to have one right now there's another one for the bargain priice of $999.99 BIN. :screwy:

I did.....

Way to go Bob. She's purdy!

Glad you got it. Those RCA projection sets are a lot of fun to get working.

Bob, you're putting plenty of miles on that truck! Congratulations on another great set.

This will be my first projection set and I'm really looking forward to seeing "what makes it tick". I guess that's what I find so interesting about this hobby...exploring all of the different, and in many cases almost unknown, technologies that make it up. Thank goodness for my trusty Ford Ranger, we've seen a lot of miles together the past few years and look forward to many more.

Way to go Bob!

I will let you restore your's first, then I will have a very high benchmark to try and achieve when I finally get around to doing mine :-)

Santa arrived early in Jamesburg, NJ. I made the 500 mile round trip to Virginia on Saturday to pick up the RCA 9PC41 projection TV.

It turned out to be a beautiful day weatherwise and well worth the trip. The set is almost in mint condition as you can see by the attached photographs. There's virtually no cabinet work that needs to be done.

As for the electronics the thought of 40 tubes and 4 sizeable chassis is kind of daunting, but I intend to go through it slowly and methodically.

The only down side is the fact that apparently at some time in it's life someone decided to eliminate the remote brightness/contrast control and simply cut the wire coming out of the back of the set. If I can't find a replacement, I'm hoping the set will work without it.

I'm kind a anxious to see just what's in the mysterious looking tank at the bottom of the cabinet.

This should be a lot of fun....I'll keep you all posted.

Bob

Wow! That's in great condition! Nice catch!

Bob,

The set is designed to work without the remote control. You will need to have the spherical mirror (in the bottom of the "tank") resilvered. The guy at Spectrum Coatings dose an nice job at reasonable prices:

The flat front-surface mirror in the lid should also be replaced for optimum performance (brightness). Front surface mirrors can be purchased on-line, and a local glass house can cut it down to the trapezoidal shape required.

Check you 5TP4 CRT for emission. If weak, look for a NOS replacement. They go by on ebay every now and then, or maybe a collector has one to spare.

Once you have recapped the set, note that the power supply and video chassis can be run on the bench stand alone for troubleshooting. Likewise, the horizontal/HV chassis and power supply can be run stand alone on the bench, though you will need to clip lead in a temporary horizontal hold control.

Then you can put it all back in the cabinet and hook it all up for final testing and adjustments. I would not recommend setting up the optical barrel on the bench, it is a lot of extra trouble to do so, and you don't need the potential x-ray exposure. But with the optical barrel in the cabinet, the x-ray exposure is minute.

The audio chassis is known to have that rotten rubber covered wire in it, so be prepared to replace some wiring. I would also recommend you replace all the chassis mount wirewould resistors with more modern replacements. The chassis mount resistors are notoriously unreliable.

One it is all tweaked up and working well, you will be surprised at what a bright picture it has.

Good luck and have fun with it!

Excellent, excellent, excellent. Glad you got it for an excellent price too. Wow, until recently, I didn't know that they even existed. Shows how little I knew...

John;
Thanks very much for the information and the insight. I feel better now knowing there are qualified experts like yourself I can turn to if I should hit a brick wall. I've got a project that I'm presently working on, but expect to finish it off in a few more weeks and then....it begins.
Thanks again for your input.

Glad to help in any way I can. Chuck A is another good resource, he and I have restored a number of these projection sets. And the good news is there is nothing in that set you cannot find a replacement for. There are lots of the sets out there (relatively speaking), and many of them are just parts sets. Aside from the crappy RCA wafer tuner, these sets perform well once restored.
