I don't know that 2.6v is a valid logic low. Several tests come to mind. Monitor the output voltage at pin 3. Zero volts. Now briefly ground pins 1,2. Does pin 3 go to a positive few volts?
Answer:
Yes 4.50vdc
QUOTE:Also at the flip flop, the collectors of Q1 Q2 should look the same. We know what Q2 is doing, does the collector of Q1 have the same voltage levels? or does it go closer to zero?
Answer:
Just to sure on this transistor it is ECB, if so the collector voltage does not change from 0 at all. I'm having a hard time figuring out what transistor it is on the schematic I see 2sc24500r but not finding anything online about it.
Or turn the selector switch over to the end position where the two lines down to the 4011 are both not connected to anything. Now, does that switching line from the flip flop still only go from 2.5 to 5? Or does it now go closer to zero?
Answer:
Closer to Zero
