I just bought a secondhand audio sonic set, very old one, I think. It came
with a tuner (STU 2000), a pre-amplifier(st 2000) and a power amplifier(st
2050) but without any manual. I checked on the internet and found nothing.
The power amplifier has a notes said that "power consumption 90 w".

I would like to know what is the output power, and what kind of speakers
are suitable for it.

Any tips are appreciated.

I asked this question in rec.audio.pro with no luck.

Judging from it's vintage and power consumption figures - maybe around 20-25
watts per channel.

A technician could test it but would usually have to charge for the service.

thanks very much for the answer. I am not going to send it for testing, the
service charge may higher then itself.

So is that true I can use a pair of speakers with RMS power 10-15 watts?
