Wiring the Output Transformer, Feedback Switch, & Speaker jacks
Step 1 – Insure that you have the TR-OT-07 output transformer (if you have a different
transformer, let us know). From the bundle of primary wires, solder the white wire to the side
terminal of the B+ fuse holder (drawing 5.15c).
Step 2 – From this same wire bundle, solder the blue wire to pin 3 of V5.
Step 3 – From this same wire bundle, solder the red wire to pin 3 of V4. Keep this red wire
long enough to reach V5, pin 3 just in case these two wires have to be exchanged.
Step 4 – Solder two lengths of 16AWG buss wire through the contacts of the output jacks as
shown (drawing 5.13a).
Step 5 – Connect the bundle of secondary wires of the output transformer to the impedance
selector as shown (drawing 5.13a).
Step 6 – Solder the black lead from the output transformer to the output jacks.
Step 7 – Solder a 3” piece of 18 AWG black wire from the grounded solder terminal G4 (at the
V4 power tube) to the output jacks (drawing 5.13a).
Step 8 – Solder a 6” length of 18 AWG wire (recycled power transformer wire is fine) between
the COM terminal of the impedance selector and output jacks (drawing 5.13a).
Step 9 – Install the two resistors on the rear of the feedback switch (drawing 5.13a).
Step 10 – Install a 20AWG wire between the 4 ohm tap of the impedance selector switch and
the feedback selector switch as shown (drawing 5.13a).
