Audio Technica AT ML-180 Cartridge Advice

The original is gold plated hollow pipe boron with tiny nude microline stylus, i have a few samples of perfectly working at-ml180 and at-ml170. I also have a few broken samples of both, one of them is here. I think the best option is Expert Stylus & Cartridge Co. service in UK, they are very good in communication and very well organized, reasonable prices (imo). Contact Email: info@expertstylus.co.uk

Here is the info i got from them:
"We shall need to carry out a detailed examination and assuming we find the cartridge repairable, our charges to carry out a complete overhaul to include materials as necessary and auditioning will be between £291.00 - £330.00. With the work carried out we aim to return the cartridge to as near new condition as possible. Should we find the cartridge in relatively good order, apart from a badly damaged cantilever or the stylus to be showing excessive wear, our chatges will vary between £120.00 - £180.00."

I use my AT-ML180 and AT-ML170 on Victor UA-7045, Lustre GST-801 and Reed 3P "12 Cocobolo. 

Thanks Chakster that is very helpful. Would you suggest Boron cantilever? Also what diamond profile.

Yeah, closer to the original, unfortunately hollow pipe boron is not available anymore in the world (which makes the original cartridge so special). 

I would use boron with microline/microridge type of diamonds. They call it paratrace. See below what they said:

"We manufacture cantilevers in aluminium, boron and sapphire. I would also advise the Paratrace profile diamond is possibly the most advanced diamond produced world wide." -ExpertStylus
