RE: Controlling amps that don't have a remote control

["Harrison, Mark (Alliance)" <mark.harrison@xxxxxxx>]

Ah - now that's clever, because it would mean that the hi-fi electronics
could be on a separate (non X.10) spur from the control stuff...

Hi Mark,

I assume you dont want to "degrade" your kit by adding any sort
of chip to
control the volume but wish to retain a conventional pot. There are
motorised pots available from ALPS which is one approach or you can fit a
motor drive to the existing pot.

You could fit a cog or pulley of some kind to the existing shaft and mount
the drive motor above or to the side to drive the existing shaft. If you
are
worried about emf/rfi then extend the second shaft outside the rear panel
of
the amp and mount the motor externally.

You could also develop the audiophile idea a bit further similar to the
amps
which have external power supplies. Use some sort of miniature hydraulic
motor with a remote pump to control the shaft. That way the electric motor
would be nowhere near :-))

Once you have a drive motor to operate, use HomeVision or something similar
to decode the IR and operate the motor.
