Cosmetic condition: 90%, some rust found at speaker plug due to rare use
Specfication abstracted from internet source:
The GFA-5800 is unlike most amplifiers as it uses only MOSFET's in the signal path. NO bipolar transistors anywhere.
It also simplifies the signal path by using only three gain stages.
