AT - 33 prestige . Is it repairable ?

Second Cpk's recommendation.

Go for it, but be prepared for a long wait. The result IME is worth it. Note that the top of the line rebuild from Soundsmith costs about as much as a new AT33PTG. However there's a fair chance that, as Cpk suggests, you will like the rebuild better than the original.

Get a second 33PTG to play while you wait! OK, this may not really be a welcome idea, sorry if so, but the AT33PTG is a really good-sounding cart for relatively little money and you'd have to spend double or more to do better IMHO. I like it as much as or better than my old Benz Glider 2.

They want to re-tip. This is a new cartridge so I want only to repair if possible.They will inspect for 75.00 and then let me know.So I am deciding which way to go as I have a cart. worth about 350.00.
Which would be best RE-TIP,REPAIR,REPLACE ?

If replace with original or something is better for about the same $$$

I would say that if it's the same price, go for the Soundsmith recommendation.
