ok. I took some measurements.

I flipped the sync inputs back to normal.


I put my multimeter on DC, and started up the CD player, and pushed pause. and powered the circuit up. The output on the IC was around 5.6v

as soon as I pushed play, it jumped to about 12.6V i pushed pause, it dropped to 11.9, but no noticable speed change on the motor. I push play again, it goes up to 12.6 I have a b+ of about 13.5vdc

if i put the syncs backwards again, it stays at 0 volts. and then itll occasionally spike to 2.4 to try to lock the picture, but quickly falls to 0v, most likely because im using the disk as the reference, and sync as the loop signal (backwards, only way it attempts to work).


If only I had a function generator, i could pump a "fake" signal in place of where the optical fork is, and see if its the circuit or the fork.
