1. General Description The Absolare Hybrid Mono Amplifier is a tube input, solid state output, hybrid design monoblock power amplifier, supplied in matched pairs for stereo amplification. The single ended tube input section is inspired by the Absolare Preamplifier using two 12AU7/ECC82 (or compatible) tubes.
2 inches (5 cm) clearance above each Amplifier to allow sufficient ventilation. Each Hybrid Mono Amplifier is designed to be supported by separate support feet. They do not have support feet fixed in place. Feet can affect the sound quality significantly.
12AU7 / ECC82 tubes have one missing pin acting as a correct positioning key. Align the missing pin with the missing hole in the tube socket while inserting. ABSOLARE Hybrid Mono Amplifier User Manual 1.2...
Amplifier can maintain output specifications into impedance variations down to 2.5Ω. CAUTION: Negative (black) speaker binding posts are not at ground level electrically. Do not connect them to chassis ground, or to each other in any way. ABSOLARE Hybrid Mono Amplifier User Manual 1.2...
6. Operating the Unit 6.1. General Operation Before turning on each Absolare Hybrid Mono Amplifier, be sure that all tubes are installed and all cables are connected securely. After turning each Amplifier on, the power indicator LED on the front face plate will start to blink.
