1 thing that is interesting; the overhang is a high 18,5mm. the arm is only 218,5mm eff. length.
i do not think that a standard protractor will work as a reference for adjusting.
i took a look at a picture of the deck, and there doesn't seem to be any adjustment possible at the headshell. maybe it is the arm base that must be positioned for the correct overhang. are there slits in the headshell where the cartridge is mounted? is there any kind of adjustment possible at the headshell?
maybe Seb can calculate a protractor for this deck.?.
the project turntable is a good budget deck with a better than average sound for its price range. it shouldn't be a disappointment. it should sound really good.don't give up, persevere. believe me, it's more than worth it. especially with all the great vinyl you have!!
