Sony Betamax SL-F30 video recorder multiple issues - Sony can be so clever!

Quite a lot covered in this one and I am somewhat perplexed several times whilst working on this fine machine but I do get there. I still think it's ingenious how the take-up spool tape end sensor is used to detect when the loading ring is fully unlaced - a real 'thinking outside the box' when that was designed.

I have to say I was pretty bemused by this machine until I realised it had numerous faults and twigged how the end sensor was being used.

Please like and subscribe - it really does mean so much to me and thank you very much for watching.
