Yes the faceplates were matched to the switch type, that is all there is to it. Availability of the switch at the time. The most prevalent has the -20dB sensitivity position on the right and o dB on the left.Before my time then...
My meters are more sensitive in the 0DB position in the Aerosmith PL700B #3. Does this mean my faceplate and switch are a match?
Lee, do you have different switches? I can only remember seeing one type.

What does your faceplate front look like around the switch.Before my time then...

It's probably worth a pint of Crown Royal.I'll get it headed your way...
There was some discussion on this years ago, IIRC it had to do with which switch was used..
This is just a theory based on my recent experience. If your faceplate has 0DB on the Left side of the Meter Attenuation Knob and -20DB on the Right side, you should have the "drum type" switch. If your PL700B reads the opposite on the faceplate, you should be sporting the "wafer type" meter attenuation switch.Like, which switch was which?
