I have Electromagnetic Transport Frequency in one of my electrical physics books. Is that it? I really don't know either.

LPMTF means Low Profile Multi-Tube Feeder and EMTF means Extended Multi-Tube Feeder. The difference is that the EMTF is bigger and it supports a wider range of tube.

Fuji CP3 and 2mm pitch tape
