The 4087 is a higher-end tube-powered model from 1962.
Being over 50 years old, it's now due for restoration, both electronically, and mechanically, in order to provide reliabile and safe service.
As I've mentioned on other threads here, it's a mandatory thing to have it serviced. (since it probably was never done recently)
Otherwise, the tubes, etc, will cook, resulting in higher-cost failures than needed.
Of course the record changer by now has dried-up lubricants that need to be flushed/removed, and re-lubricated properly.
The rubber components (motor mounts, idler wheel) are most likely dryrotted and need replacing.
The cartridge/needle would need replacing as well.
Overall, you're looking at around $300 to get it up to par, if no tubes are weak, and much more if a power transformer or output transformer(s) blows due to faulty dried-up capacitors.
Unplug it, stop trying to use it, and safe the added grief of a real expensive restoration.
The Internet is a marvelous thing, however it's not a good substitute for actually being there.
