GS-G 203 vs CS 77A

First post noob here, but wanted to get feedback on what folks thought I should put money into. Picked up a set of GS-G203's that need a new 4" mid-range (OEM $38 pm ebay) and likely foam on both and a set of CS 77A's that need the foam on both tweeters replaced. Connecting to a Pioneer SX -727 tuner primarily for a turntable. It there one worth investing in more than the other? Thanks for any feedback

CS-77A years of manufacture 1972-79 Sealed Acoustic Suspension 8 ohm - real Walnut wood veneer
CS-G203 years of manufacture 1991-92 Ported Bass Reflex - 6 ohm - simulated wood grain vinyl covering (1991-92 was not Pioneer's heyday)

I have the CS-99, CS-99A, and CS-A500, all from that same era 1970-1975. I served in the Navy during that time period, and the speakers of choice in my barracks were the 77A's. Have never owned any of the CS-Gxxx series speakers, but have seen some in thrift stores and yard sales - the build quality is crap compared to the older CS-77A.

Without hesitation my choice would be the 77A. and they match up with the vintage of your receiver - SX-727 produced 1972-74
Does your 77A have the correct 'FB' cones?

You can get a set of foams for the 77A tweeters for under $20. I wouldn't spend $38 on the G203.

Much appreciated JamVal. Yes clear quality difference in the make between the 77A and G203. The 77A does have have FB cones. The surrounds on the 77A are not foam...so I guess they don't need replacing like the tweeter. The tweeter surrounds crumbled to dust when I touched them. Thanks for the information and for your service.
