====== BT LTU16a ====== {{ rb:ltu16a-top.jpg?400|}} \\ Unusual LTU as this is in a metal case. No real indication what it does except for the marking on the top@- " 'A' Line Services". This seems to be a passive unit with transformers and capacitors presumably for line equalisation. Certainly a simple unit. {{rb:ltu16a-inside.jpg?400|}} {{rb:ltu16a-sockets.jpg?400|}}
