Project Solstice Operation Guide:

Normal Operation and Notes:

- Plug in the amplifier and then the power supply (in that order). Make sure the tube, headphone jack and input RCA's are

secure. Once the amplifier is turned to the ON position, the front red LED (closest to the volume knob and headphone jack)

will illuminate red for approximately 45 seconds. This indicates the protection circuit is active while the tube is warming up.

It may take several minutes for the tube to fully warm up depending on the tube type used

- When the protection circuit activates and de-activates, a slight click may occur

- When the power switch is turned on and the amplifier is plugged in, the LED under the tube will illuminate

- Depending on the tube type chosen and the sensitivity of headphones used, background noise (hiss) may be present.

Choosing a higher output impedance setting, or a lower gain tube can generally eliminate any background noise with

sensitive headphones. This does not mean a high gain tube can not be used in our designs. Selecting a higher output

resistance or lower input gain setting may reduce noise with higher gain tubes. We advise you experiment with several

tubes to find out what you like best

- If load testing Project Solstice, it is not recommended to attach a dummy load with a value below 15Ω when testing at full

output power for a long periods. Heatsinks and the output devices at the bottom will become quite hot during testing. The

amplifier will go into thermal protection when chip temperatures of 150oC are reached. Under normal conditions (playing

music) even when driving low impedance loads, the output devices will get slightly warm at best.

- Some channel imbalance below 9 o'clock on the volume potentiometer is normal. We recommend you adjust your source

output levels and use Project Solstice with a volume setting of 9 o'clock or greater. If headphones are to sensitive and

volume range is limited, you may order a replacement quick change attenuation module which simply plugs in. This will

allow proper range on the volume potentiometer

- Some faint scratch when turning the volpot is normal. This does not indicate a bad volpot – just a micro amount of DC that

is present with certain tubes. This type of scratch is generally only heard with no music playing / rotating the volpot

- Cell phones or radio frequency devices in close proximity to Project Solstice may create noise that is audible when

listening to music (generally clicks or digital noises)

- Clean your Project Solstice with a microfiber cloth and plastic cleaner (dusting with a microfiber cloth is generally all that is

required). Compressed air is also great option for dust.

- Hot swapping tubes is not recommended (swapping tubes while the amplifier is on). Even though it does not cause

technical errors or malfunctions it could damage headphones rated for 1W or less.

- NEVER ADJUST THE OHV JUMPER WITH THE AMPLIFIER ON.
