The original was a professional unit manufactured for use as a microphone amplifier, phono amplifier, etc. It had high gain, and for use as a standard audio line amplifier, the gain was optimally modified for home use based on advice from a professional. At that time, maintenance was also performed, making this a very valuable item that allows you to fully enjoy the ALTEC sound as a vacuum tube monophonic line amplifier.
Includes custom-made walnut cabinet.
Includes two phono amplifiers for the same product (these were included at the time of purchase, but their usage is unknown).
Vacuum tubes used: GE 7025. Each unit has 2 tubes, with 1 RCA input and 1 RCA output each.
Therefore, a separate selector and LINE cable are included as a bonus (RCA input: 3, RCA output: 2).
*It was used at 115V using a step-up transformer. While it can be used at 100V without issue, it is believed that closer to the original voltage of 117V is more suitable for fully enjoying the ALTEC sound. Different expressions can be enjoyed at 100V.
