Hi Larry,

ALC is an input on transceivers, not an output.
The output is on the linear amplifier to reduce the output power of a
transceiver if necessary by supplying a negative voltage.
Modern transceivers have a power control itself so ALC is not required
anymore, just leave ALC disconnected.

  Subject: Questions: Connecting a Drake Amplifier

 Hit a roadblock I am not understanding. I wanted to connect a Drake L-4
Amplifier (also have a Drake L-7 - same problem). Looking at the input the
unit/s want - they want AGC input - I am familiar that ALL other Amplifiers
I have used accept/require ALC input.  I am trying to drive either of these
units with a ICOM IC -756 - it only outputs an ALC
