How do we play 78s
Let’s pretend that hitherto, you had little or no knowledge of 78 rpm discs – but yesterday, you found a small pile of them at a car boot sale for very little cash, and bought them purely out of interest. Or perhaps your grandmother gave them to you instead of just throwing them away?

In any event, after looking at them all, you wondered what they actually sounded like. Indeed, you wondered what you would need in order to play them.
Well, the good news is that the Internet contains acres of advice & recommendations on how to do so. For instance, there is an excellent article on playing 78s by the distinguished sound engineer Roger Beardsley.
By the way, the CLPGS is the British national society for gramophones, phonographs and the records played on them – if your interest in old 78 rpm discs is – or becomes – strong, you should almost certainly consider joining it! Details are on the site above, and you can easily join on-line & pay the modest subscription by PayPal.
