TSE 118 ?

Only problem is that a Fane 18XB will not fit in a TSE118 as the magnet fouls the loading trap door---18XB cones also disintegrate when used in them at reasonably high SPLs

Robbo, you've just reminded me of how tight those chambers were. Mr Andrews was hung up on making things as small as possible, and I remember we had to groove the hatch doors on some of the cabs so that the magnet would fit. He would have loved Neo in those days.
