AK Member DGWOJO should have them.
If you pull the receiver up and out, you can access the openings in the pots where the leads enter. This is where the De-Oxit needs to go. Just spraying the tops won't get it where it needs to go.
The speakers look the same as the ones in my 65 Futura. The Faceplate is similar but the controls and switches are reversed (top to bottom) from the 590. I DO LIKE the angled top for the control center. Mine is flat. Guess the 59A/59T combo was a one years shot. Your's is a "Receiver" where mine is a PRE-AMP/Tuner (59-T) and and AMP (59-A).
Like Red said: R=Right, C=common or neg, and L=Left for your speaker connections. Use U lugs or solder the ends of the speaker wire and "loop" them tightly around the screw and tighten. The loop goes clockwise (if you think of a backwards "?" that's what you need).
Clean all the contacts. The push switches are the most problematic of the controls I have on my Futura. Also the OFF/ON switch. If you can get a power strip, use it.
You might want to consider a recap if your gonna use it a fair amount. Power supply, and signal path caps. Tuner caps shouldn't really need too much work as they are mainly ceramics IIRC. Those two caps on the speaker X-over will give you the most bang for buck sonically based on my Futura. Use the same or as close as you can get value caps. The mids and highs will balance out a lot better after the caps are replaced.
I had SP-2000 and SP-200 Sansui's (rotated) working the EXTERNAL hookups on mine. They sound a lot better than the original speakers with the original caps. But the improvement with new caps has caused me to re-evaluate. No externals right now. But I did find some FISHER WS-1's for designed for Center fill. I use them about 6 foot out from either side of the console and a lot of empty holes (sonic wise) across the wall disappeared. And that DUAL 1019 is no slouch either. Get a new stylus, clean it mechanically, and you'll be set.
Does it have limitations? Sure, but considering what was available in 1966 for the average household it's a good unit. Much better than average. One hell of a lot better than most of the rest of the stuff that was selling as "Hi-Fi" or Stereo then. It was designed to be fairly simple to operate, had most of all the popular gear in the cabinet, and was expandable. Plus it's a good looking piece of Furniture. Granted it's NOT as powerful(sonic or visually) as a separates set-up, but owning a Console was a sign that you were pretty much "comfortable". And Consoles had a High WAF(Wife Exceptance Factor) back then. They had to look good and pretty much match for furniture.
Get some "Howards" Restore a Finish. Rub it in per instructions. Then go over it with Howards Feed and Wax. You WILL apply multiple coats as the 1st 2 or 3 will soak in. Let it as the finish is more than likely dry. 5-6 coats rubbed in will probably be enough. Wait a month then give it a good waxing with Butchers Bowking Alley Wax (Semi Gloss) or Johnson's Paste Wax(High gloss). Buff to Sheen desired.
Don't Use Pledge or spray furniture "wax". You CAN use Endust on a cloth, then Re-Buff it once a month or when ever it looks dirty. Toothbrush in the corners works good.
Very Nice example. With a recap and a good FEED and Waxing, it'll look as good as it'll work.
Here's a couple of my '65 FUTURA VI (F590-W)
