Install: 270pf cap in C5, .1uf in C6, and .015uf in C7

At the Mid Tone Pot, bridge pins 2 and 3 which are the holes closest to the Power and Standby Switch. Use part of a lead clipped from one of the components already installed. I like to bridge the pins on the solder side of the board

After these mods your amp will not make sound with all of the tone controls all the way down. This is on purpose! What you're doing is changing the tone stack to a vintage style which gives you a greater range on the mid pot.

DEVILLE ONLY: Install the 330 ohm power resistors at R85, and R86. Install them so they sit off the PCB by about 1/4 inch. Make Sure the leads are bent about 1/16 of an inch off the resistor

DELUXE ONLY: Install the 470 ohm power resistors at R85, and R86. Install them so they sit off the PCB by about 1/4 inch. Make Sure the leads are bent about 1/16 of an inch off the resistor

At R51 install the 91K Resistor. Install 100K resistors at R52, R4, R9, and R18

The small blue MLCC caps can be identified by the 3 number cap code printed on them in very very small lettering, I have to use shop glasses, a magnifying glass, AND a bright light to see the numbers. The first two numbers are the cap value and the third is the decimal point. The 270pf is marked 271 for example.
