SPLIT/SHARED CATHODE switch is to select between the earlier shared cathode
(330uF/820 ohms) configuration for V1, to the later split cathode (330uF/820 for V1A, and
0.68uF/2K7ohms for V1B).
TONESTACK switch is to select between the earlier 56K slope resistor + 250pF treble
capacitor, to the later 33K slope resistor + 500pF treble capacitor configs.
SEND is the Send jack of the effects loop, which is a SOLID STATE BUFFERED type, in
this amp. A ¼" instrument cable is used, to the Input of your effects.
LOOP ON OFF switch is to turn the Buffered Loop on or off.
RETURN is the RETURN jack, accepting the Output from your effects, using ¼" instrument
cable.
IMPEDANCE SELECTOR three-way rotary selector. Set to the position that matches the
impedance of your speaker cabinet.
NOTE – if you are using two speaker cabinets in parallel (ex – two 16 Ohm cabinets), set
the impedance selector to half that of a single cabinet (in this case, 8 Ohms).
