Polytone Mini Brute III loose part

[Rambostarr]

Hi! Picked up a Polytone Mini Brute III ~1987 nonfunctional at a yard sale. Have since made it produce sound by doing obvious solder repairs and wiring work. But have one loose part that came with it, no idea where it would belong. Hope someone here knows more then me, or can point me in right direction. Part is marked .01z ulr

Thanks

We prefer you not duplicate posts on the forum, one is enough. I think technical talk is better than garage talk on the whole...
