Since that time the output tubes have had one hour of use only to test the amplifier's function. The driver tube brands are a combination of "JJ", unmarked, and "USA made", (brand unknown).
The interiors of the two amps differ because one was originally a stereo amp which was factory converted to mono. The cases are generally in good condition with some exceptions. One faceplate has some minor dents. The bottom of the cases have some scratches but they are not visible when the amps are in use.
The paint is chipped at the rear of one case. Both amps have some scratches near the input and output terminals. In all instances see photos.
Other than noted above the cases are in good condition. 80 W output into 8 ohms, 50 W output into 4 ohms.
