This listing is for the gel filters which can be found behind the meters of your McIntosh amplifier.  This will help restore the blue color of the meters when the amp is on.  As the amp ages, the filters turn green, then brown from the heat of the lamps.  this causes them to glow green/white.  by replacing the filters they will glow blue again.  Please note this is for the rear of the meters in front of the light box.  this will not work for the front of the meters as that is a plexiglass panel.  there is enough material to replace 2 standard size meters, trimmable for smaller models.  If you are unsure email me with your amp model and I'll make sure you get the correct size.
