Hello, friends. I picked up a Tascam 424 from someone recently and I am unable to play tape. I opened it up and it seems I've run into many issues.

Check out my video: youtube. com/watch?v=CIIKR3I4KM4

The positive:
-Capstan belt and Take-up reel belt seem okay
-Mixer operates fine
-Solenoid seems okay. The metal core was actually loose in the machine when I got it... I popped it back inside the Solenoid.

The negative:
-When I press PLAY, FF, or RW, it only spins for a few seconds. Sometimes it takes multiple presses to even roll.
-The capstan motor isn't spinning (wrong name? the black wheel on the inside)
-The tape heads do not engage
-When I manually lift the heads and press PLAY, it plays extremely fast.

So what is wrong with this thing? Does it come down to replacing one part or many?

Thanks for reading
