Linn lp 12 upgrade or new TT ? please help.

Thank you all for comimg to my rescue.
I found out today my linn was made in 1985, and as far as I can tell, it has not had any work done on it ina very long time, I am going this way, New arm board, New suspention, new oil, new belt, and am contimplating the Hurculies power supply,the K 18 cartridge is only about a year old, it was new and had never been used when I got it.
God help me I have broken down the lp 12 now and have ordered the parts, except for the Hurc.
Any other sugg ar every welcome.
Thanks Alan.

I added a lingo at a cost of around $ 600.00 and think it was a great improvement.

Get a new, thinner mat. I forgot to say that I am ordering one. Martin Colloms, who has used the LP 12 for 20 years recently changed and said it was the best improvement for the price he has ever made. My Linn is also from the 80s and I am also changing the belt and oil. I am ordering the mat from a shop in Scotland I found on ebay as I couldn't find the mat on sites here.

New. Upgrade is a costly route that will generally not produce the same change.

Lingo = yes
Cirkus/trampoline = no
Belt change = yes
New mat = yes
