Hello all,

I am getting into records players and saw an ad for a "Zenith SFD280R" they were asking $100, however, I am not sure what the value of this type of console player is. I was wondering if anyone could help me with this? I have done a lot of google searching and cannot find anything on this specific model. Any help would be appreciated and sorry if this is the wrong section to ask this in.

From what I know, the record player works, however, there are some issues with the radio knobs, not turning. I don't mind figuring it out and trying to fix it.

Is this a good buy?

It depends upon how well you like the style of the cabinet, and the condition of the cabinet.

That's the high end of the market for an unrestored set which needs repairs.

But it's a well designed set electronically, and would sound good when complete. Figure that anything of that age will need the electrolytic and any paper capacitors replaced at the very minimum, and it's likely the record changer will need service as well.

Welcome to the Phono Forum.

The Zenith SFD280R dates to 1960.
It is a vaccum tube amplifier circuit using one EL84
output tube per stereo channel.

If the cabinet and aesthetics are mint, and
you really like the record player, then
$100 is not a bad price.
If there has been no recent electronics
service to the Zenith, then bargain down
the price.

Here's why:
All the electronics of the radio and amplifier
chasses will need to be checked.
All old electrolytic and wax/paper or other
similar capacitors should be replaced.
Some tubes may need replacement.
Same with some resistors.

If the radio tuning gang dial cord is broken,
it can be replaced easily enough.

The record changer which is probably made
by The Voice of Music, will need to be
dis-assembled & cleaned, and probably the
idler wheel and motor mounts replaced.
Possibly a new phono cartridge installed.

Once the Zenith has been restored, it will
perform well for many years.
If you decide to buy it to restore, I can
give you with the circuit schematic and
record changer service file.
The amplifier chassis itself is a relatively simple design,
and service would be pretty easy on it.

Hey Again,

Thank you all for the good information! I ended up picking up the console player for $50. I was watching a lot of how-to videos on restoring this console (Similar model) and I think I will be doing a lot of the things you guys recommended.

The console came with an extra speaker that matches the console which is nice! I will need to sand the tops and recoat them as they do have some damage.

A couple more questions.

1. Should I invest in a tube tester or just buy all new ones for the console?

2. Can I please get those schematics that you mentioned?

3. Should I just buy the tubes and capacitor from eBay or is there a specific site where I should purchase them from?

That's a great buy for $50 and the satellite speaker !

1. Tube tester: if you locate a local vintage radio club near you,
I'm sure a member would let you bring the tubes for testing.

If you plan on doing more projects with tube amps, a tester would
be a useful investment.

Check here for reasonable price tube sources:

2. PM me with your email for the schematic & service manual.

3. DO NOT order from ebay.

Use an electronics supply business such as Mouser or Digi-Key,
I use Mouser regularly, and have always been satisfied with them.

Would this be a good option for oiling up the wickers on the motor? And for all other parts that would need oil?

I do not like 3-in-1 oil and have seen it cause items to gum up prematurely.

Turbine oil is a much better choice and available from many local hardware stores in a plastic bottle with a zoom spout. Sewing machine oil is another highly refined non-gumming oil which is readily available and can be used for phono motors. Both of those are used by professional technicians for a reason.

I found the exact one at my ACE hardware store. Thanks a lot for the picture.

One of the plastic cable brackets broke on my turntable while doing the full teardown (Old and brittle plastic). I created a new one and freeCAD and printed it out. It does the job. I attached the file and image of it here if anyone else wants it. Not sure if adding the file worked though.

What is the best way to print out new lettering or decals for the manual dials and print of the EQ nobs? Any articles in here that give more information on this? The ones on my console seem to be fading and not as clear as they once were.

Hey everyone, I have been having a hard time finding a replacement mat for my zenith SFD280R. I have a found a lot of 12” and 7” mats… but the 9” seems rare.
The one on my table was old and breaking off.

Anyone know of where I could get one? Or is it standard to get a 12” and cut it down to size?

Or does my zenith player use a 7" mat? I measured the diameter or the plater itself and it was 9" so I'm sorry if I got it wrong here.

Gary at the voice of music has platter mats in
different diameters.
Your changer should use a 9 inch diameter.
