This arm came off of a Vinyl Nirvana modified Thorens TD-150mk1 and works 100% with smooth operation, I would give the condition a 9/10.
This arm has some upgrades:
RCA Interconnect wiring replaced with Cardas DIN plug and Gepco VDM250 low capacitance shielded cable and Rean RCA connectors. The factory grounding terminates into the left channel from Rega; this arm now has separate grounding with a ground lug just like most commercial turntables. Cable length approximately 54 inches.
The end stub and counterweight were replaced with high quality stainless steel pieces, I am unsure of the brand.
I do not have original packaging however I will absolutely pack the arm with utmost care.
At my asking includes shipping CONUS.
Also have a Michell fingernut and vinyl nirvana acrylic armboard for td-150 mk1 or mk2; it is near-mint outside of a few faint lines that were honestly there when I got it from new. Let me know if you are interested in either of those as well!
