Yamaha MT120 Tear Down

Here is a tear down of a Yamaha MT120 muklttacker, a four track cassette recorder.

Its the first, and and at the time of publication, the only one i've worked on.

It has more or less the same transport as a Marantz PMD 740 so refer to my videos on that for more detail on the cassette player, especially the dreaded error message.

Nice build in some ways (very clearly annotated PCBs) but not others (ribbon cables - eeewwww).

This isn't a review but I will say it seems like a weird feature set to me - no per channel EQ but master buss graphic eq....really?
