Step 8
– On the inside of the chassis,
install a #6 flat washer on the screw
near the chassis edge.
Step 9
– Install a #6 KEPS nut on this
screw (not overly tight, so the socket
can slightly rock back and forth in the
grommets) nearest the chassis edge
and seal in place with a drop of
fingernail polish (photo 5.6e and 5.6f).
Step 10
– Install a #6 solder terminal on the
opposite screw.
Step 11
– Secure the solder terminal with a
#6 standard nut (not overly tight, so the
socket can slightly rock back and forth in the
grommets) and seal in place with fingernail
polish (photo 5.6f).
Installing the V2 – V6 Tube Sockets
Step 1
– Prior to mounting the preamp tube sockets (V2 and V3), slightly bend the solder
terminals 1 - 3 and 6 – 9 outward as well as bend terminals 4 and 5 together (photo 5.6a).
This is for the preamp tubes only. Do not bend the 4 & 5 pins together for the power tubes.
Step 2
– Bend the mounting edges of the tube socket inward to allow installation of the
screws (photo 5.6b, c, and d).
Step 3
– Insert the tube socket from the outside of the chassis and rotate the socket so that
pin 6 of the tube is closest to the chassis edge / corner.
Step 4
– Insert a #6 x 1/4” screw into each mounting hole of each socket from the outside of
the chassis and secure the socket on the inside of the chassis with a #6 KEPS nut.
Step 5
– Repeat the above steps for V2 through V6 tube sockets.
Installing the Faceplate, Input Jacks, Controls & Switches
Step 1
– While holding the faceplate against the front of the amp, install the first vibrato
channel LO sensitivity input jack (the one deeper inside the chassis). The jack should be
installed with one fiber washer on the inside of the chassis and the solder terminals should be
facing toward the normal channel section.
Step 2
– Install one fiber washer and a grounding washer on the second vibrato channel high
sensitivity jack and install this jack with these washers into the chassis above the previous

Refer to the “Cool Modifications”, Chapter 11 section for modifying the amp from the 9 pin
EZ81 rectifier to the more versatile OCTAL rectifier options.

The terminals of these sockets are fragile and will easily break if bent too far. It is
recommended to use needle nose pliers for better control when bending these terminals.
