I found a Dual CS508 ULM turntable at the local Thrift Store. It still had the AT cartridge installed utilizing the Dual 1/2" adapter. I made a simple repair but upon testing, the cartridge had no output. I removed the headshell adapter and found that "fatigue" had cause the adapter to crack causing a loss of contact with the tonearm connection. I had bought to 1/2" adapters from ebay and transferred the AT cartridge to the new adapter and mounted it back on the tonearm. The turntabled played perfectly. As a matter of protocol, I ordered a new stylus from LP Tunes that fit perfectly. Thank you for still having this stylus in stock.
As posted by a previous reviewer, I found that the headshell is angled a bit uphill, so I had to compensate by raising the tail of my SME tonearm a bit. With just a touch of twist of the cartridge, it lined right up on the protractor and cartridge tracking is excellent. Sonics of the MP-500 thus far are excellent.
