SETUP SHEET FOR PL2A AMPLIFIERS

Use these handy sheets to mark your switch positions for various setups. Each switch position has been “blanked” out so that you may place an “X” or a check-
mark to indicate the setting of each switch for future reference.

Copy these blanks so that you have several copies.
