Installing Chassis in Cabinet
Head Cabinet
Step 1
– Place the predrilled 18W cabinet
head, face down on the work bench with the
rubber feet facing toward you.
Step 2
– With the tubes installed into the
chassis, insert the chassis into the cabinet
with the knobs facing down toward the
bench.
Step 3
– Loosely install all the screws with
washers through the cabinet into the
corresponding press nuts mounted into the chassis. Do not tighten
until all screws are properly threading.
Step 4
– Once all the screws and their washers are loosely threaded,
center the chassis in the front opening.
Step 5
– Once the chassis is properly centered, tighten the four
mounting screws to the cabinet.
Step 6
– Finish the installation by attaching the rear panel.
Step 7
– Your amp is done and ready for you to connect it to a
speaker cabinet and play.
Combo Cabinet
Step 1
– Remove the power tubes and the rectifier tube from the
chassis.
Step 2
– Rest the chassis on its transformers with the knobs facing
toward you.
Step 3
– Lay the back panel on top of the chassis with the cutout of
the panel facing toward you.
Step 4
– Loosely install all the screws with washers through the back
panel into the corresponding press nuts mounted into the chassis. Do
not tighten until all screws are properly threading.
Step 5
– Once all the screws and their washers are loosely threaded,
center the back panel opening to the front panel controls.
Step 6
– Once the chassis is properly centered under the back panel,
tighten the four mounting screws.
Step 7
– Turn the back panel and chassis over and reinstall the power
tubes and rectifier tube (It is really difficult to install the tubes with the
chassis already in the combo cabinet).
Step 8
– Install the chassis and back panel assembly into cabinet with the knobs facing up.
Step 9
– Connect the 1/4” plug from the speaker in the cabinet to the speaker jack of the
chassis. Make sure that the proper impedance on the amp is selected for the impedance of
the speaker.
Step 10
– Your amp is done and ready for you to play.
