Need to replace my Technics SU-X501...

Question

Hi,My old black amplifier is unrepairable and I now need to replace it with something compatible for my Hi Fi system. I'm not bothered if it has to be a different colour as long as it works with all the other components.My old one has the plug in connections at the rear. I don't want to go mad price wise,but want something powerful to match everything else....please help.Single Mum.
