BOOST/DRIVE FTSW
Using a TRS cable, connect a two-button, latching footswitch to this jack
to facilitate remote switching of the Boost and Drive functions.
LINE OUT
The Line Out provides a buffered preamp output to another amplifier or
to a console for recording.
POWER AMP INPUT
The Power Amp input provides a direct injection point for the 6L6 power
amplifier in the Delta King 12. Plugging into this jack interrupts the
connection between the preamp and power amp, allowing players to use
different preamps or modeling hardware to achieve an unlimited variety
of tones while still enjoying the Class-A warmth of the Delta King tube
power section.

2.4 TROUBLESHOOTING
Supro products have been designed for years of trouble free service. There are many unique protection features to
the design. If you are having difficulties, check the following:
No sound, but pilot light is ON
Check to see that the speaker is plugged into the speaker jack (not the footswitch jack). Make sure all knobs
are turned up past zero and that the Standby switch is set to operate. As this is a tube amplifier, the tubes take
approximately 1 minute to warm up before you will get sound. The Standby switch should be set to standby for this
warm up period.
No sound and the lights are all OFF
Unplug the power cord and check the 3A,250V(100V-120V); 2A,250V(220V-240V) fuse.
