i think you misunderstood what i am looking for.I am looking for the banana plug terminal that is part of the transformer where the wires with male banana plug ends   plug into the transformer terminals

Patrick,

If you look closely, the positive and negative banana terminal are part of an entire assembly.  These are the same that are used in the TIU. YOu might be able to reassemble that dual terminal assembly to replace the single damaged binding post but once you have the Z4000 apart it may be easier to replace the whole thing.

See my picture below: The one on the left was removed from an early defective TIU and the one on the right is a replacement from Radio Shack:

You can buy the entire replacement assembly from radioshack.com: https://www.radioshack.com/search?q=2740718

Tell you what, send me an email with your address and I can send one that I have salvaged from a TIU.

 

UPDATE:

Yes they can be completely disassembled see below:

First of all,thank you for your quick response.I was doing a little research and i came to that conclusion about about the ones from the TIU are the same.I would be very grateful to you if you did do that kind offer for me and I accept it 100%.If there is anything that I could do for you,I would do my best to return the favor. Am I allowed to give you my email address right here ? I am not sure how hard it is to open up the transformer and replace it,but I will try.

I'd look twice at the Radio Shack part, it doesn't seem all that robust!  This is a transformer that delivers up to 10 amps from each output, looks a bit anemic for the job.  Don't know why it has such a low rating...

When I have a truly dead TIU, I just pull all the usable parts off, and the binding posts are one very useful thing I get from them.  Several Z-4000 transformers have them now.

Yeah I'm not sure why the Radio Shack part is spec the way it is. The internal screw terminals are slightly thicker than the salvage MTH terminals and they also have just a bit more weight to them.  the eyelet holes on the binding post are just a tad bigger than the MTH version which allows for larger wire to inserted through the post. Otherwise they look dang near identical.

I load tested the one pictured above with an 8 amp load at 16 volts for an hour and didn't notice any detectable failure point or heat build up.
