  • InA frequency electrical practice there may be established on the transformers 13 and 14 windings such that the capacities 17, 18, 19 and 20 (more particularly the capacities 17 and 20) may be omitted.
  • a connection has moreover been shown in the drawing between the plates of the audions 3 and 4. This connection is established through the capacity 23. Its object is to increase the amplification if possible. Quite generally, it should be conceived that for the purpose of obtaining this result the connection between the plates of the audions 3 and 4 may be made with a self-inductance 27 in series with a capacity.
