These AY-3-891x amplitude levels are being used in the “Free Unix Spectrum Emulator” emulator.

The original comment below:

 /* AY output doesn't match the claimed levels; these levels are based
  * on the measurements posted to comp.sys.sinclair in Dec 2001 by
  * Matthew Westcott, adjusted as I described in a followup to his post,
  * then scaled to 0..0xffff.

These are more linear than AMPS. AyFuseAmps struct implements FUSE_AMPS for AmpLevels.
