1.#General#Description#
The Absolare Push-Pull Amplifier is a transformer coupled, zero feedback, two
chassis monoblock stereo amplifier with an all tube signal path and point-to-point
construction. Transformer Balanced (XLR) and Single-ended (RCA) input versions
are available.
2.#Safety#Issues#and#Warnings#
- - Ensure the voltage setting of the unit matches the voltage of the available AC
power. Operating voltage is fixed and must only be changed by an authorized
service agent.
- Do not touch tubes while operating. Tubes are extremely hot devices and also
contain very high voltages.
- There are no user serviceable parts inside the units. Do not open bottom covers.
- Do not operate the amplifier without an output load. 4 – 8 ohm speakers or
equivalent load should be connected to speaker terminals when the amplifier is
operating.

3.#Unpacking#and#Placement#
The monoblock amplifiers are supplied in separate boxes. After opening the top
cover of the box, remove the upper layer of hard foam material. You can then lift the
units from the box using the cloth underneath each chassis.
Feet can affect the sound quality significantly. Feet should be placed directly under
the aluminum base plate, not the MDF/leather plate. There are three areas where
the aluminum base plate is exposed through openings in the bottom MDF/leather
plate. These areas are where feet should be placed. You can use either three or four
feet. Adjusting their position will also affect the sound to varying degrees, depending
on the type of rack, location or interaction with other equipment. For most situations
the arrangement as shown in the diagram below is a good starting point.
