Greeting - Ended up with a Navy MBF small transceiver. Need a drawing or where on the net I could down load it. Learned from Hue [Thanks] the MBF is a bit unique as its a couple watt 70 Mhz AM rig with a design that includes 115 volt AC/DC line operation with all the tube filaments in series like table model radios of old. Thanks 73 Bob W7AVK
