DCC134 Belt replacement?

Hi, First post here so be gentle.

I bought a DCC134 spares or repairs cheap on eBay - looks great, almost perfect in fact but wanted your opinion on the fault please:

It powers on fine - when trying to play tape I hear a gentle pulsing whirring noise but screen does not come on nor is there any playback.

My guess is hopefully it just needs a new belt. Should I be looking at anything else as the potential issue? I have watched the YouTube video about replacing the belt so am under no illusions to the task ahead of me - lol.

Hi and welcome.

Sounds like the belt for sure.
Normally that is the first thing.

Thank you. Yep, new belt now fitted and playing loud and proud!
