1. AC Power Entry Module:
Accepts standard IEC power cord (included)
for 115v or 230v AC mains supply. A fuse is included with each unit for
the voltage/current expected at the location being shipped to. Only use a
fuse with the same rating and voltage as marked on back of chassis.
2
. AC Voltage Slide Switch:
Each unit is factory set to the voltage ex-
pected at the location being shipped to. If voltage does not match mains
voltage at your location, switch to reveal the appropriate voltage. Do not
operate unit set to incorrect voltage. Harm to the unit may result.
3. Model/Serial# Tag:
When registering your product for your 2-year war-
ranty, please use the hand stamped tag to obtain the serial number.

CHANGING TUBES
Each Model 286A will leave Locomotive Audio with a new set of tubes
that should last for several years. We encourage you to utilize these
tubes, but also experiment with with other brands of New Old Stock tubes
to acheive your sounds! There are no rules with brands or age of tubes.
But be sure to use only EF86s or EF806s and 12AY7 tubes in the appro-
priate tube sockets. This will prevent any issue with the performance of
the 286A and damage to the unit.

. Mic/DI Switch:
Allows for selection of either the xlr mic input on the
back of the unit or the DI jack on the front of the unit.
10
. DI:
The Direct Input jack is useful when connecting high impedance
instuments such as guitars and bass. This 1/4” instrument jack loads
the source with an impedance of 169kΩ.
11
. VU Select Switch:
The VU meter on the 286A is able to display the
output signal level of either channel 1 or channel 2. If set to the center
position, no metering of either channel will be displayed. This is especially
useful when slamming the final gain stage and output transformer. An
analog meter is expensive and can be damaged if not treated properly.
