screw from each side of the cabinet; disconnect r everb and speaker wires, then slide the chassis
toward the rear.
2. TUBE CHART:
3. OUTPUT TUBE BIAS & BALANCE ADJUSTMENTS
A. Warm up the amp for 2 m inut es with ST AND BY OFF and the OUTPUT POWER set to FULL.
Set SPEED and INTENSITY TO “ 1 ” and make sure TREMOLO is OFF. Flip the STAND BY switch
to the UP position.
B. Remove the bias controls cover box.
C. Set BIAS: with a DC voltmeter m easur e VDC between GND and V9&V10 test points. Adjust
BIAS for .06 VDC (60mVDC).
D. Set BALANCE: measure the VDC between V9&V10, and V11&V12 t est points. Adjust
BALANCE for zero (0) VDC.
E. Replace the bias controls cover box.
