Has PM Stereo 200 on the front and PM Stereo 100 on the back. It worked in a quick test. Has lots of fuses inside and out.I can't find any info on it.It has Martex corp. WA. Any Ideas?
Have I got a story for you about Martex. The gentlemen who was the one of the co-owners is someone I know. He has some history with another significant audio company that started in Seattle back in 1970. Please contact me for more details.
