Help a noob replace a very old receiver!

My husband is a huge audiophile, and a long time ago he inherited a record player set up from his dad. The receiver he has is a Sansui stereo receiver 881. It is hooked up to a Sony direct drive turntable system 2251. Unfortunately the receiver is broken add needs to be replaced, and I thought it might be a good present for his 40th birthday. Can anyone suggest a good replacement for this type of old receiver? Ideally less than $500? Any assistance would be very appreciated!

I got this solved,.

Personally, I’d have had it fixed - but I do prefer old gear to new
