Hi all! I have a Beogram 8000 Type 5613 where the platter spins way too fast. I’ve been able to narrow it down to the HEF4013BP Flip Flop IC. I know very little about logic chips, and what I do know I learned yesterday, but I can see the speed sensor pulses going in and nothing coming out. VDD is stable around +5V. Are modern replacements like a Toshiba TC4013BP pretty much the same or are there specific values that I need to look at when choosing a replacement?
