What are the specifications of the Sony LBT A-50?

Question

Sony

Good day!
Decided to buy a vinyl player, chose Pro-Ject. I was especially interested in the Pro-Ject Debut Carbon model (frequency range 20 Hz - 22 kHz, signal-to-noise ratio 68 dB, MM cartridge). But without an amplifier and acoustics, this device will be of little use.
I found with my parents a Sony music system, model LBT-A50, with very nice bookshelf acoustics (purchased in the 90s). The technique is working. The system was rarely used for its intended purpose.

There were no manuals, nothing informative could be found in the search engines, and I myself have never contacted sound equipment, so I would like to know:
What are the technical characteristics of the amplifier of this system (is there a phono stage, is the amplifier suitable for working with modern players, maybe you should choose another player)?
I would be grateful for any related information/recommendation!
