Recommendations for repair/sale of vintage speakers, turntable etc

[Anonymous]

Somewhere recently, I saw a recommendation for someone who would fix or maintain old turntables and speakers, etc.

I have some for my dad. My kids are a little bit interested in keeping them, but they are very large and I don’t have much room. If we can get a good price I’m interested in selling them.
I feel like someone who knows a lot about them would be a good resource to help me out with that.

Any recommendations?
