Tascam MF P01 Portastudio - Gav Tries to Fix (with video)

I finally bought a cassette based 4 track, which is a thing I’ve wanted since about 1994. I found this bare-basics Tascam on eBay as spares and repairs. It was sold without a power supply, and the seller said “Not sure if working as I haven’t got a power supply for it, so it’s a bonus if it does!”

Well, turns out it DID work, however, things were GRIMY in there, so I set off to clean it.
