Messenger 2v 10 meter amp. Used, not tested by me. It has two transistors. I don't know what the transistors are, but you can see the top of the motorola logo on each one. I got this amp as part of a package deal with a 10 meter radio (Magnum 257). Before I bought it the seller demonstrated the setup for me, and got a good report on 10 meters ssb with this amp and the magnum. All I really wanted was the radio. I thought I would use this amp somewhere, but never did. Now I just want to move it for $ for other radio gear. It has an inline fuse and about 10 feet of 12 or 14 gauge wire. It has some velcro on top. $55 shipped conus only. Paypal only.
