The left-side switch [20] activates / deactivates the boost of the Classic channel.
The right-side switch [21] allows to switch from one channel to the other.
Note : the footswitch has priority over the panel switches. When the footswitch is connected,
the front panel boost and channel switches are not operational.
9. Maintenance
No maintenance is needed, apart from a tube change (to be done exclusively by an authorized
technician) once the tubes are worn.
In case a tube change is needed, no bias setting is required. Indeed, the
Crunch Machine
uses
cathode-biasing, which is auto-adjusting.
The
Crunch Machine
is complimented with JJ-Tesla tubes. You can use other brands, as long as:
The power tubes (V4 and V5) are matched
And you use the following types of tubes :
o
V1, V2, V3 : 12AX7
o
