I found a fuse and the picture is below, It tested ok
But I think I found the problem
It looks like this post has come off the board (not sure if this is considered a board, but it has come off the base)
Is there a trick, or part that can be used to get this post and the wire it connects back connected?

There are two green wires in the picture. The one on the right (above the 3) is attached properly on a post that is there to competes the connection. The one on the left, you can see the wire, its connector, and a silver stick/post. The post is supposed to be sticking up. The post has come off the base and has broken the connection
The post is still with the green wire on the left. I think you can see it better in this picture
I have fixed this with an ugly solder connecting the wire back. The tape deck is now working, sort of.
Now the belts seem to be slipping.
Without a tape in, it will "play" FF and Reverse. With a tape in, it will fast forward, not reverse and not play
Should I start a new thread asking for a tutorial on changing belts?

well done in getting so far .. next thing is clean the pinch-wheel .
also check the belts . cleaning the wheel might just get it going though ..

just thought ..if the tape isn't moving in play its more likely the belts .
the pinch wheel is what feeds the tape through . if it was slipping the tape would maybe run through quickly . the wheel is on the open side of the cassette .to the right of open side at the bottom of the deck . black rubber wheel

it really depends on what it is worth to you .
you could measure the belts and maybe get them cheaper . i know you can here .

IMHO it is worth the money and effort to fix. I would get a rebelt kit and change all the belts and do any lubrication called for at that time. Get a service manual.

Two Questions
Can anyone confirm the belts that I need for the Dual C 919?
I found that the three belts needed are
fry 10.0
ox 5.5
scq 6.7
I have found I can order them on eBay by searching Dual C 919 belts
but I found this site, and can order them direct, if I have the correct belts.
The price difference is significant, because of shipping, but I am also wary about trusting someone in Germany to package the correct belts together

So I had all the belts replaced by a tech.
He calls me up and says that the motor must be bad because of excessive wow and flutter
He cleaned it and lubed it, but it will not come up to speed
He was surprised to see that the same motor on this Dual tape deck is in the Dual turntable
Anyone think it is worth looking for a replacement motor? How difficult would it be for me to change the motor myself?

I have a few Dual turntables for parts. See if you can find out what motor you need and maybe I can help you out. Or maybe it doesn't matter what motor you use

Just let me know if you need something

Here are the photos of the motor as it sits in the Tape Deck
I don't know if I want to mess with it. I had a tech put in new belts
No identifying marks to tell if the motor is the same

motor looks serviceable . may be limited to lubrication due to lack of parts but maybe all it needs .
