For 35 years, I'm an Audiophile wanna be

Back in the 70s, I bought DQ-10s, DQ-1W, Audio Research D76a amp and SP3A-1 pre - I am the original owner. Also, a still alive Technics SL-110 table with Grace 707 arm and F9L cart (which also needs replacing). I've been "dormant" for 20 years. The D76 is now declared dead and the SP3 needs a makeover that could cost $1500 - more that it's value. Due to space issues and aesthetics, I want a pair of Maggie 1.7s. So CALLING ALL SOUND JUNKIES: 1) Should I repair the SP3? If so, what is a good amp to hook to the SP3 & Maggies? If not, what do you suggest? Not looking to spend top $$$ but understand I must spend something....I know some of you salesfolks wanna sell me something but if it's out there, I'd like some thoughts - not pitches. Thank you my fellow music lovers!
