Yea, thats a nice looking set! looks to me, there is a dosen more to go through!

My grandmas 50th anniversary color from RCA looks similar to that, but its a rectangle tube, with folding wood doors. still plays perfect today, tube has been replaced. looks very similar.

Last night, I jerked the HV tubes and brought it up on the variac. I never made it past 85 volts because i could feel, hear, and smell one of the lytic cans getting hot. I was still able to tune in audio pretty good, so, looks like this cool-cat will be coming back to life!

Just got off the phone with Moyer's... ordered a new flyback. I was in luck... got the last Thoradson they had on the shelf for this model.

I had examined the old flyback a little closer last night. It looks like it had some serious issues. Melted wax, burn marks, corroded wire going to the 3A3.

Did a quick clean-up job of the cabinet. It's looking much better. I will go over it again later paying more attention to detail.

Does anyone happen to know the name of this model? Model number listed on the back is 14G896MV.

Tonight I decided to pull the chassis from this RCA. The flyback was toast, so I swapped it out with a good one I pulled from another chassis. Underneath, I found a terminal strip that nearly fell apart. Looked like it got baked from a nearby 10 watt resistor. Had to replaced all the wires that became brittle, replaced the terminal strip, and repositioned the resistor to the side of the strip instead of directly underneath it. Changed most of the lytics... still got one can left to go.

Was quite late, so, I decided to go ahead and plug it all in to see how things were. Got high voltage and a picture on the screen, but the raster only fills about half of it. I was a little disappointed that I didn't get a full raster because I did change the 50@150 on the verticle board. In the past, I've always found most verticle height problems are corrected when changing this particular lytic. Oh well... I at least have something so far. The horizontal doesn't lock... it seems to be off just a tad.

As far as color... not doing good there yet. Two of the tubes on the color board wont light up... a demodulator and the osc. Tried changing them, but still wont light. Maybe the sockets just need some spray in them. I'll dig around for that later.

Although I haven't hooked up the meters to check it, it seems the flyback is running nice and cool. At least that much is good.

At least I've got it running and nothing's smokin yet. Still got plenty of work to do on it... not to mention need to take off the safety glass so I can clean out all of the old crap that held it in place at one time.

Stay tuned.

By name do you mean like the "Grenoble" or the "Harlequin", etc...I'll look in my RCA field service guide and see if I can find it.
