Hello, welcome to NLG.
We don’t see a lot of conversation around these machines on this forum although someone might jump in.
One other thing, your photos did not load. Attachments need to be less than 1000k each and total attachment size no greater than 5000k.
I sometimes find it works better to load one image, then go back and edit my post and
add another image.
I use a free app called Photo Compress, others text or email the pictures to themselves which usually compresses the photos.
There is a company called Captains Auctions in Anaheim CA. They sell a lot of redemption machines at their auctions, they might be able to refer you to a resource for parts and such.
Please keep us posted.
Chris
