Hi Jim: Someone did find a source for the 22 vdc battery so you should have that info shortly. My AF 67 uses three 9 vdc batteries and a couple of hundred K resistor to get the bias dead on. There is space on the top of the chassis on the right had side to velcro in the 3 battery pack. I'm running my AF 67 with a Swan MK2 amplifier and Collins R 388 for 200 watts of carrier. The old Elmac is a very reliable AM transmitter and I'm sure you will enjoy it. 73's Greg WA7LYO Kinston NC ----- Original Message ----- From: "Jim Wilhite" <w...@brightok.net> To: "AM Radio Discussion List" <amradio@mailman.qth.net> Sent: Saturday, November 07, 2009 8:31 PM Subject: [AMRadio] Bias Battery
