I didn’t measure a short across them; neither in circuit nor with one leg lifted.
They read the correct value (within specs), and there is no resistance reading with one leg lifted.
TTL Chips will measure a low resistance from vcc to gnd whenI have replaced ALL the chips on that main lower board, except for U270 & U272 which I couldn’t find.
This is frustrating as hell.
I have yet to check for a signal on pin 10 of U330.
