The BA25 is a two channel stereo booster/buffer line amplifier with up to 25db of gain. Uses include boosting consumer .316dbv output level to match a .775dbm (0db) professional input, interfacing vacuum tube equipment to solid state equipment or placing in the audio chain to provide extra gain control. The BA25 amplifier is built on a 2mm thick anodized aluminum flat chassis plate, lettering on the chassis plate is engraved. The chassis plate, secured onto the black metal base, is removable making all wiring easily accessible. Except for wires from a couple components, wiring in the amplifier is durable Teflon™ insulated. Ground points are all wired together eliminating the chance of a poor chassis dependant ground connection.
