Thanks for that– and one update, I verified the cart is ok–the cartridge has 770 ohms measuring both ways-measuing pins horizontal and veritcal. measuring the din conntector–The Din connector–between pins 2 and 3, I get the 770 ohms, but between 2 and 5 I get nothing. I should add that the Din measurement was taken while a record was playing, with cartridge. thanks so much for your thoughts.
