I need some help in locating 9 , 14 pin female card holders that go in the bottom of the deck in the amplifier section. Looking for possible sources for GOOD new or used 14 pin female card recepticals. Teac part# 50438380 . There is no locator in the receptical nor a locator notch on the boards. This is a 1974 mastering deck that is out of the box looks and function unless it gets moved a little. Plastic recepticals are cracking open due to age. I know I am asking a lot , but any help in sourcing needed parts would be great. THANKS in advance.
