Restoration of an old vinyl player




In the attic of the house, the master found an old record player, which had been lying there for about 20 years. Many parts and connections were oxidized and damaged, but when turned on, the engine was running and the drive was spinning. Then the master decided to try to restore the player using parts from other devices.

Tools and materials:
-Player;
-Dremel with nozzles;
-Sandpaper;
-Compass;
-Screwdriver;
-Pliers;
- Clamps;
- Brass profile;
-Gas-burner;
-Boards;
-Plywood;
-Fasteners;
-Glue;
- Hacksaw for metal;
-Veneer;
-Knife;
-Degreaser;
- Paint tape;
- Electric jigsaw;
-Drill;
-Cardboard;
-Plastic;
Water-based varnish;
-Brush;
-Acrylic;
-Aluminum plate;
- Potentiometer 22K - 2 pcs;
-3 position switch;
-Nadfiles;
- Brass plate;
-Double sided tape;
-Drill;
-Polishing disc;
-Polishing paste;
-Aerosol spray can with paint;
-Silver solder;
- Brass tube;
- Iron rod with a pointed end;
-Tweezers;
- Borax;
-Pipe cutter;
-Drilling machine;
-Soldering iron;
-Wire;
-Crown on wood;

Step One: Disassembly
First, the master disassembles the restored player, and the donor players.








Step Two: Hole
A new tonearm will be installed on the player. The old master removes and cuts a hole for the new one.



Step Three: Brass Profile
In the new design, the master decided to use brass parts. Heats up a brass profile and bends it with a ring. Glues a ring around the disc of the player.



Step Four: Veneer
Now you need to paste over the body with veneer. Measures the front, back and side walls of the housing. Cut veneer to size. Apply glue and fix the veneer with clamps.






Glues veneer on various parts of the player.










Before pasting the upper part with veneer, the master closes the holes with plywood inserts, and smooths the uneven surface by gluing cardboard on it.



Now you can stick the veneer to the top.








Step Five: Varnishing
Covers the veneer with varnish in two layers.Between the layers, sand the surface 220 with sandpaper.

Step six: support the tonearm
The tonearm and mount will be installed from another player. The master cuts off the excess plastic parts of the support. It polishes the surface with large emery paper and pastes it with veneer.












Seventh step: spacer
To raise the tonearm and, accordingly, the head, the master cuts and sets a spacer from acrylic.




Step Eight: Potentiometers
The old 22 kOhm potentiometers and the 3-position switch were replaced by the master with new ones. Fastened them to an aluminum plate. I drilled holes for handles in the case. Secured the plate to the body.





Step Nine: Decorative Details
Prints a pattern on paper. Fastens it on a brass plate with double-sided tape. Cuts out. Next, the part must be sanded, polished and, necessarily covered with varnish.






Glues the pattern. Cuts and pastes an arcuate decorative trim.




Step Ten: Gold Painting
Stains the details of the head, counterweight and disc in gold.







Step eleven: parking place for tonearm and pen
The master made pens of brass tubes soldered to brass plates. Then the handles were turned, polished, polished and varnished.




The master also makes a rack for parking the tonearm from brass parts.









Step Twelve: Final Assembly
Before disassembling the player, the master photographed the installation of the electrical part. After installing new parts, the master solders the wires in the same order.


Then cuts the bottom cover out of oak. Paints it black. Cut and screw the legs. Screws on the lid.




Sticks on the handle.


All is ready. It remains only to install the needle and the disc, and enjoy the vinyl sound.

There was a branded device, but it became - it is not known what ...
(The device did not add values, rather, it lost it.
That's the point of the colleague, that the original apparatus does not represent a special rarity. Just massive plastic consumer goods - an inexpensive imitation of a turntable. Valera, I understand very well! I myself love tube radios and old technology. And here for the surroundings you need something older, but better a gramophone! I myself store for restoration a lamp player-suitcase. Two lamps in the basement of a cardboard case covered with faux leather, an unimportant speaker in the lid, wheezing and hissing, but it looks more colorful!
And somehow I was making a summer cottage from the casing of an old (very) TV. You could insert a tablet there, but I wanted it to be black and white and round. And therefore, for a long time I was looking for the old (relatively))) small car TV ... Lucky - the diagonal of the screen coincided almost one in one. (Although the old building was six times larger in area of ​​the front wall))))). Little I fixed inside with the case))) Entirely.)))) ...
Image is bad! The sound - not really ... The cord - and he cut it off, and instead of it put a messy twisted of two single-core with a black plug.))))
... There the whole room was "retro" ... With outdoor wiring on ceramic rollers, a light bulb on the ceiling, a bed with a stack of pillows under lace "wraps", curtains on the windows and rugs woven from rags on the floor ....
So it happens that we’re not chasing characteristics))))
getting a sound significantly different (for the better, understandable)
This is not for sound, this is for fun! smile
I completely agree with my colleagues, a vinyl turntable is a lot of nuances, first of all - accurate (and therefore expensive) mechanics, a good non-resonant body and details of the mechanical part of the system. It makes sense to bother with this only in the case of a task - getting a sound that is significantly different (for the better, understandable) from a good CD. The model of the experimental turntable is similar to the profanation of an idea - everything is plastic and light. First of all, it would be worth spending your time and work on damping the case, light “ringing” parts, shortening the wires, removing unnecessary contacts and rations from the signal circuit.
Let me bring you description of their own similar works.

A few words on the decoration. In addition to the above, imitation of everything in a row "under the tree" is very cheap. Polished brass (patterns) looks much better on dark. By the way, you can cut them with a jewelry jigsaw from a sheet.

an attempt to make a Mercedes Lada :)

Michael, frkf; tw
master, would you look closely at the player - maybe it's still metal, not vinyl.

The brass pattern is an absolutely superfluous part, quite laborious to manufacture if laser cutting is not used. The inscriptions disappeared. It was enough to cover the table with veneer and restore the rest of the details to their original appearance.
Judging by the fact that absolutely no attention is paid to the correct installation of the tonearm, it seems that you are right.
"But what about the strobe marks?"
What are these tags? This "relic" is gilded - hang on a wall (or under glass). Entourage for the apartment ...
So many extra, uninformative photos, and not a word about the method of cutting:
Prints a pattern on paper. Fastens it on a brass plate with double-sided tape. Cuts out
Then cuts oak bottom cover
Judging by the photo, this is metal!
It colors the parts of the head, counterweight and disk in gold
But what about the strobe marks? scratch
Restoration is the restoration of its original form and characteristics, in this case we have an assembly of two turntables of a certain hybrid.
I didn’t like the lack of signatures of the controls and the dust collector on the top panel, it looks like it was randomly squeezed out by silicone “snot”.
