Do you know if a reel motor was ever replaced or worked on?

And is this a new problem? In other words since you've owned this 388 did it used to act normal and then for no reason, with no cause or event, it just started misbehaving?

Wow Skywave that info is awesome. I'll check it out, and thanks Sweetbeats for identifying the diode for me. To answer your question, this is a unit that has sat in a warehouse for an amount of time that is less than 16 years, but long enough to get pretty messy. I recently came across it and would like to get it going. The spiders are cleared out of it now. But really, you and I have the same amount of knowledge about this particular unit.

I can't remember if I shared this already, but I did replace the capstan belt last week and it made no difference.

Edit: Ugh, shameful double post.
 
I'm assuming you have re-seated the power supply and reel servo cards, yes? And double checked for bent connector pins? Sorry if you mentioned that already and I missed it.

If you've done those things or you do them and there's no change, I'd be checking what is happening on the +24V transport power supply when you try and engage PLAY. Even though the transport quits, the logic still thinks it's going. Maybe the transport supply is faulty and the voltage drop is enough when a load is placed on the supply that there isn't enough current available to hold the transport mode. That's what I would check first. Always check the power supply first.
 
Maybe double check the fuses too? If it's sat that long, or did someone already mention it.
