Nice Betamax you have there. Here is the one I currently have.

Alas, not in pink. I’m tempted to find some speakers to hook up to give the amp a whirl someday.
Yours is very cool also. For a consumer deck, I have had no problems since I bought it. I have at least one other working player for an emergency. There’s nothing like a Beta. Did you ever get into ED-Beta? It was just too expensive for me at the time.
