Someone here wanted an AM-8/TRA-1 amplifier a while ago. I brought one back from Missoula, Montana a month or so ago. I also found the manual(s) I needed for this amp with its power supply. (Thanks Robert) This amp appears never used. Still has the all the tubes in it, and it is mounted in a large wooden box. Please contact me if you are still interested. Ken Gordon W7EKB
