The Sparkos Gemini Headphone amp/Preamp is a remarkable device. Well built & awesome sounding.

Описание: The Sparkos Gemini Headphone Amp/Preamp is a phenomenal unit. It sounds very, very good as either a headphone amp or as a preamp. 5 Stars. Sorry for the poor audio. Ironic isn't it?

You can use the following tubes in the Gemini:
• 6922 This is the stock tube that the Gemini Comes with
• 12AX7 Popular guitar amplifier tube, lots of tube harmonics
• 12AT7 Similar to 12AX7 but biases harder and with more current
• 12AU7 Similar to the above two, but biases harder still. Has lower gain
• 12AY7 Similar to the above, but biases with less current
• 6AQ8 Originally an RF amplifier tube, odd order harmonic dominant at high volume
• 5751 Similar to 12AX7 but with less gain
• 6CG7 Old school vertical deflection amplifier for CRTs, slightly longer length
• 6N1 Has a hot heater and lower harmonic levels
• 12BH7 Popular in McIntosh amps, slightly longer length, mostly even order harmonics
