This was the other console that I got for free with the Astrosonic.  I believe this is a 1961, it has an MPX adapter for FM Stereo but it does not have a tape input. The speaker lineup for each side is an 8 inch and a tweeter.

I like the looks of the cabinet, has a nice style and color.  I recapped the amp/preamp, still need to work on the tuner; AM works, but FM is dead.   If I can't get FM to work, I will disconnect the tuner and run bluetooth in through the tuner input. 

I haven't been able to find anything on these, seems to be a standard compliment of lower mid-level RCA components.

That sure looks like a 1962. I have a pair of 1961 models with 3 channel amps, no stereo adapters but that tuner is similar to mine. The knobs and escutcheons are different for 1962 models than 61's.

Wanted to edit post but here is what I wanted to add:

The tuner is a German-made pull-string tuned unit just like Motorola and some others used. Normally very good in Motorola, but the ones in both my 61 RCA's are not good. One cannot seem to tune below 89 mHz without messing up the middle band when I try to follow the alignment procedure in Sams.

My first recommendation is to look at the strip of soldered connections under that tuner casting. You may need to heat up solder joints and check B+ volts is present. There is an AFC switch connection and some others but ground, B+ via the bandswitch and output to IF amp could cause the symptom of Dead FM.

If AM works, its grounded and tube heater is ok at least.

That is a nice looker, I hope you can get it up and playing the way you want.  And, even though it's single ended it should sound nice.

Looks to be in good shape! The "higher end" Mark models had the PP amps and the tuning eye in an oval part of the escutcheon, those are fairly common. Don't see this nice SE model as often.

I'm hoping Trevor shares a video of it playing when he gets it done.  I would love to hear it.

Discovered why the left channel isn't working on it, the speaker lead separated from the terminal connecter at the speaker.  Looks like a bad solder job from the factory.  Just need to pull the speaker and the wiring and reattach.

I do need to order the cartridge kit for it and get that installed, thankfully the idler is in good shape.  I need to pull the tuner this week and get started with that.  Not really a fan of RCA using a bloody snap ring to keep the platter installed...  That was fun getting off without a snap ring plier.

It's a wonder the snap ring didn't end up someplace where it was lost for ever.  Usually the #%$@#% comes out when that happens.

I think those fall into the category of "Jesus clips."

I have ordered the Cartridge kit for the changer and have ordered speakers, brand new Jensen speakers from their Vintage Ceramic line.  I went to remove the other speaker and the pot metal retainer/rivet that holds the speaker clips to the speaker chassis just broke off, the leads to the speaker then broke off, basically this is what happened to the other speaker, but no one touched the other speaker. 

I went with new speakers as I was having problems finding a matching pair of 8 inch 4 ohm speakers, both separately and together...  Sweetwater had these for sale with free shipping, so I figured I would give them a try.  They are also half the cost of the new Jensen AlNiCo 8 inch speakers and only about $10 more per speaker than old speakers that were pulled from another unit.  https://www.jensentone.com/vintage-ceramic/c8r

It looks like you made a good choice.  I like the link you sent, it allows one to listen to different types of music thru the speaker.  That's cool!

The speakers are installed in the RCA,  I installed a new cartridge, and it works!  https://photos.app.goo.gl/occ24Z49HdiDFz1c7

I discovered that there is no way to adjust the tracking weight of the arm, and with the new cartridge it tracks too light, hence my added weight LOL

I discovered that an old capacitor is about the right amount of weight to be added. I glued one in, but must have bumped the wire to the cartridge, and when trying to reattach, I broke the pin off of the cartridge...  OY! I have an extra cartridge to install, that'll be this evenings project

I also discovered that the radio is dead dead, 99.9% sure that is has a severe case of Silver Mica Disease in the FM section. Given this revelation, and that there are no AM stations around here, the tuner is not going to get connected.  I removed all of the tubes, disconnected the power, removed the multiplex unit, and wired in a Bluetooth receiver into the tuner input. The tuner will remain in the cabinet for looks only.   

It sounds awesome on Bluetooth, forgot to get a video on that last night. 

The only other thing that I need to do is figure out a new lid prop, the original one is shot and does not hold the lid up anymore, I have also never seen one like it before.

I have a few RCA consoles that use that same tuner. RC-1192 IIRC. Not their best work at all and I don't blame you for de-commissioning it.

The 1963-64 RCA consoles used the RC-1205, a much better unit with on-board mpx and a 6FG6/EM84 tuning eye. The  4VF349 I sold picked up AM especially well, even daytime.

Yep Dave, I think that's the one I had once, mine had the "hutch style" cabinet with the speakers mounted up high and the EM84 tuning eye.

Another job well done Trevor and it does sound good.  It's too bad the tuner is screwed up.  Good luck with your search for the lid support.
