[Drake] TR-7 to amp question

    Which contacts on TR-7 can control the keying
 of linear amplifier?  I can build a buffer relay
 if needed, or Ampkeyer would be ideal.

    My copy of schematic is fuzzy and I am not 
 using the PS-7 power supply which has the con-
 tacts for keying.

    Many thanks to all for the great help in the
 past.
