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.

That turntable is pretty long in the tooth.  If it were I, I would look into something new, like the new Technics SL1500 turntable for $1199.00.  I would think a cartridge in the $300-400 price range would match nicely.  There are also many used tables here which may be more to your liking. 
I suggest: Take a photo of that TT, put it on the shelf with a photo of the Dr's who made a difference, then ceremoniously toss it!

Direct Drive, Quartz Locked speed, New or Vintage, if you like wood look probably Vintage. There is a new Denon wood direct drive, perhaps others.

If Vintage, I would ask specific advice here first.

New Cartridge. I would stick with MM unless you already know about MC, it's a tricky and pricey world I just learned/entered.
The AR, if it is in good working order is surprisingly good.  The arm looks rather agricultural, adjustments are rather clumsy and the only antiskating is provided by the twist of the tonearm leads, but it works well.  The headshell mating pins wear quickly so push it into the arm and then tighten the collar rather than using the collar to draw the headshell into the arm.
There is tons of information out there on how to restore, modify, or upgrade ARs, but it sounds like you might be satisfied with a simple refurbishment, which you might do yourself, though there are reputable people who focus on AR restoration.
Look at the suspension rebuild parts available at Vinyl Nirvana. I rebuilt the suspension  of my AR "the Turntable" (1984 mfg. date) three years ago. Not difficult or expensive and the results were amazing. You can also replace the motor if desired - but not necessary.

I would suggest you consider replacing the tonearm with a vintage SME or Jelco. No essential but better than the AR standard.



the arm is the problem on the table

it sooo affects the sound
You can always replace the arm If you want, but I must say properly set up that’s an excellent table.  Keep it.

I use my 46 year old 1229 everyday.  It’s my favorite component.
The AR is likewise excellent.
