There is no pricetag on happiness !
Really, ?? You suggest spend whatever it takes to try and restore a worn out console with a mediocre turntable that is probably eating up the records, possibly dried out speakers, and questionable electronics? And "try" is the operative word here because it is not a given that it will succeed.
If something you can do yourself and you want a project then fine, give it a go. But to "hope" that whoever you can find to take this on will succeed is not a good strategy. It will take a competent tech many hours and a lot of parts to do it right, which equates to waaaaay too much $$.... and even then you will be left with a subpar performer
time to move on
