Line I/P2 and Line I/P3
If %T210A or %T210B is fitted without a centre tapped transformer (usual configura-
tion), these lines can be shorted together or left open to be used as inputs to the audio
cavity.
If %T210A or %T210B is fitted with a centre tapped transformer, these lines must be left
open. Line I/P3 becomes the centre tap on the transformer.
If %T210 is fitted (Pot core type), short these lines together for normal operation.

Note: Figure 1.4 above shows the standard pin allocations for the T800-03-0000
auxiliary D-range kit. A T800-03 auxiliary D-range kit is also available for
special applications requiring custom internal wiring.
