Awesome console! I wish I owned one....Especially if it had a color roundy built in.

I got one a few years ago for a 1962 Motorola Console I sold and it was just right output for that funny little pre-amp Moto's have under their controls I just ordered another 710 to replace a failing E-V 186 on my 1959 Zenith's V-M changer.

I just went and ordered a one of those cartridges. If the postman doesn't deliver it to the wrong place and lose it (like happened with some capacitors I ordered last week), I could be listening to records on this next week.
I still have to do more cleaning and lubricating, I just did enough before to get it so it would play manually. Not that I ever put a stack of records on and actually use the changers, but it's nice to have it all working like it should. And I just got in my crossover caps. I suppose after I swap those caps and finish with the changer I can put it all back together screw the chassis down and put the back on even if I don't have the cartridge yet. The horns don't say Zenith while the other speakers do, and I did have a Magnavox with horns. It was a 1965 color roundie combo with a solid state stereo. The stereo sounded great, and it had a nice cabinet, but the fly was bad and the 21FJP had a green gun with an open filament. I wound up junking it, I think I sold the horns...

I replaced the crossover caps. I never used to bother with those, but as I recently discovered with my other Zenith console, they really make a noticeable difference. I guess they get leaky and let too much low frequency sound in the tweeters.
And I zeroed out the bias on the outputs, even before adjustment there was at most only a few tenths of a volt. Tomorrow I'll get back to the record changer.

It all works now except for the cartridge. I put everything back together. I think it is so unusual to see an old radio or TV console where those cardboard loops that are stapled to the cabinet and hold the wires together were all intact, that I preserved them and put them back.

That Zenith model is very worthy of such professional restoration.
I have two 1964 Zeniths to work on in the next month or two. Since these both use single-ended 6BQ5 amps and all four of the Zenith Amperex-sourced tubes tested good, biasing on the outputs should be easy.

Does anyone know what the part number is for the turntable belt for this unit? It started playing slow, and I'm thinking it's probably the belt slipping as I lubricated it before, and I never changed the belt. All my sams are stashed in boxes in the garage I still haven't sorted through since I moved here last year. I don't know where I stashed the manual for this and it'd probably take me days to find it!

Unfortunately there were a couple of sized belts depending on the model of the changer. Look underneath and you should see the changer number 169-xxx. You can use that to look up the replacement belt. There might even be a 32-xx number for the belt needed (Zenith part number). You can cross reference that to the correct one. If memory serves me they used a 20.6 inch or a 21.6 inch belt. You can tell if it's the Zenith "Professional" belt drive changer by the 45 RPM adapter built into the platter. Good luck!

If you know the Sam's number and it is below 580 I can look it up. I've got Sam's 101-580 near complete and some random stuff before and after...All neatly sorted in file cabinets.

Adam - I think I have a manual for this record changer, please confirm the 169- number.
