Vintage ARxb turntable. Refurb or replace

Hello fellow music lovers. I am asking advice as to whether I should refurbish my vintage 47 year old ARxb turntable or replace. I primarily stream Qobuz through a Bluesound streamer 
and McIntosh MA7900 and SVS Ultra Towers and subs. I have an old record collection but rarely use my TT as it has a hum that needs attention. My question is Refurb or replace. I figure Refurb may cost 3-600 and a budget to replace is 1500 give or take. Sentimental value is high as I bought this TT new in ‘76 after recovering from a severe case of Guillain Barre Syndrome and is the last part of my first major purchase (long gone Marantz2270, AR2ax speakers. I do not plan on changing my streaming habits as I love finding new music. I also used my album collection for a Jazz radio show many years ago and the studios needles were unkind to my albums. Thank you.
