Hey there!
I do have one. I have a few to be exact lol.
I got the same BS from TE and it really made me mad. Hoping I can help a few people out.
I just posted one for you on reverb.com just a few minutes ago if you would like to purchase (url below)
Let me know if you need any other keyboard related parts and will post.
Hit me back if you have any more questions.
