Hi-- as I'm 35yrs older than my first system, I suggest the following:
The amplifier can be improved upon.
OTOH, repair and keep the tuner.

So, should I repair all this and connect my TV and a CD player to itYes, repair those speakers well. Check the crossover components too. Google yr speakers, ther must be information on maintenance and tweaks.
or should I sell the whole thing and buy a theatre system? Should I repair everything before I sellListen first, modern spkrs sound impressive but overall poor performers. Good spkrs are expensive & you have good sprks albeit aged.
