Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
To ensure proper ventilation always make sure there is at minimum four inches (101.6mm) of space behind the rear of the apparatus. The ventilation should not be impeded by covering the ventilation opening with items, such as newspapers, tablecloths, curtains, etc. Do not impede ventilation by placing objects on top of the apparatus which extend past the rear edge of its cabinet.
Please contact Supro directly or a qualified person for tube replacement.
The AC plug is the mains disconnect. The plug should remain accessible after installation.

2. ANATOMY AND USAGE

2.1 FRONT PANEL

IN

Instrument input for the amplifier.

VOL

Controls the volume level of the amplifier.

TREBLE

Controls the treble frequencies.

BASS

Controls the bass frequencies.

REVERB

Controls the volume level of the spring reverb effect.

SPEED

Controls the speed of the tremolo effect.

DEPTH

Controls the depth or the amount of throb in the tremolo effect.

WATTAGE SELECTOR

Switches between 1W, 5W and 15W of output power.

STANDBY SWITCH

This turns on the high voltage to the tubes. The tubes should warm up for at least one minute before turning standby switch to OPERATE. Be sure that the Volume control is set to a reasonable position before switching the amp to OPERATE as this amp can be very loud! For short breaks (5 minutes or less), using the standby switch will increase tube life.

PILOT LIGHT

This shows that AC Mains voltage is flowing to the amplifier.

POWER SWITCH

Turns on AC power to the amp. The Power switch should be turned on, and the pilot light should be lit for 1 minute before turning the standby switch to OPERATE

REAR PANEL PEAKER

The Amulet provides one 8 Ohm output for the internal speaker. There is a second speaker jack that is also wired at 8-ohms for a total 4-ohm load when two 8-ohm speakers are connected.

TREMOLO/REVERB FTSW

Allows remote shutoff of the tremolo and reverb effects via latching footswitch, using a 1/4” TRS cable. You can also use a Single Footswitch with a 1/4 TS cable to control either the reverb or the tremolo. With the cable pushed in all the way, the footswitch will allow remote shutoff of the Reverb only and the Tremolo will ALWAYS be Off. With the cable pushed in half way, the Reverb will ALWAYS be On and the footswitch will allow remote shutoff of the Tremolo only.

IEC POWER CORD RECEPTACLE / FUSE HOLDER

The power cord connects here and to your country’s appropriate wall outlet. Make sure to connect the male end of the IEC POWER CORD into a Grounded Power Outlet. This IEC connector contains the AC Mains fuse. This is a 5x20mm, 2.5A, 250V Fuse.

2.3TUBES

Each Supro tube amplifier is a 100% analog, 100% tube amplifier. There are NO solid state (transistor) devices in ANY audio signal path.

2.2 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 2.5A, 250V fuse (rear panel).
