Technics HiFi cheap from flea market?

All started from Technics intergrated amplifier SU-V6X it was 25€ with Cassette player RS-B48R and turner. But seller says there is problem with sound because there was no sound?! It takes me and my son 2 hours to figure out problem with it. Loop wires are missing from behind, everything else is ok.
Speakers are B&W DM 630, bought from recycling center for 40€.
Then came CD it is SL-P170 4€, nothing special about it but It'll do until I find a better. My brother was looking for CD and i gave him my spare one, and in exchange I got Technics SH-8045 EQ. My latest flea find is Technics turntable SL-5310 price tag was 14€ but i didn't notice that it was -50% discount, so 7€ for it. There was no needle at all but new is ordered less than 30$. New better parts are welcome all the time for example cassette deck update for RS-B965 and CD SL-P10.
