UTC2050L

Evening all, Found these at a local place, I have run them on +-26 VDC, they seem to work fine. Looks reputable ? UTC ?
Any experience on these chips. Had a Sony 212 to repair and the original chips are long gone, LM1875 chips were not available at that moment for an emergency fix, so I used them. Ha1350 were the old chips.I know the old original TDA2050 are not made any more.
Regards
Jan
