Mod Wave - Step 7: Connect Reverb Driver & Components

13
Strip and tin a 2" length of the blue hook-up wire and connect it from T4(4) to V4 pin 1. Solder the T4(4)
connection, now.
When making connections to the tube sockets, the filament wires should be low and touching the chassis
surface. Try to make all of the other tube pin connections from above and routed through the air so that the
wires and component leads do not touch the filament wires.
Strip and tin a 9" length of the blue hook-up wire and connect it from T3(1) to T8(5).
Step 7 – Connect the reverb driver wires and components
The V2 socket will hold the tube that works in conjunction with the output transformer (TR2) to drive the
spring reverb tank. The pins of this socket must be connected so that the two triodes of the tube are connected
in parallel with each other (plate connected to plate, grid to grid and cathode to cathode).
Strip and tin three 2" lengths of blue hook-up wire and connect:
V2 pin 1 to V2 pin 6 (plates)
V2 pin 2 to V2 pin 7 (grids) – Leave room to connect two more wires, one at pin 2 and one at pin 7.
V2 pin 3 to V2 pin 8 (cathodes) – Leave room to connect a cap and resistor to pin 3.
Strip and tin a 2" length of blue hook-up wire and connect it from V2 pin 2 to the footswitch jack’s tip lug.
Warning: Be very careful not to burn the insulation of nearby wires with your soldering iron.
Strip and tin a 3" length of blue hook-up wire and connect it from V2 pin 7 to T8(7).
Connect both a 1.5K resistor and 25µF capacitor from V2 pin 3 to the locking lug as
shown in Drawing 5. Make sure to connect the positive end of the capacitor to pin 3.

Strip and tin a 9" length of blue hook-up wire and connect it from T8(7) to the mini-toggle switch’s B-side
pole lug.
Cut a 3" length of blue hook-up wire. Strip ½” of insulation off of one end and the usual ¼” of insulation
off of the other end. Tin both ends and connect the ½” end to both “T-off” terminals on the mini-toggle
switch. The other end connects to T7(2).
½” ¼”
Connect a 220K resistor from T8(7) to T8(8).
Step 8 – Wire the phono jacks
Strip and tin a 9" length of blue hook-up wire and connect it from T9(1) to the center lug of the “Phono
In” jack.
Strip and tin a 11" length of blue hook-up wire and connect it from T9(4) to the input jack’s “shunt” lug.
Strip and tin a 9 ¾" length of blue hook-up wire and connect it from the output jack’s “shunt” lug to the
center lug of the “Phono Out (2)” jack. Leave room at the “Phono Out” jack for one more wire.
Strip and tin a 2" length of blue hook-up wire and connect the center lugs of both “Phono Out” jacks.
