The Wilkinson, after many years as our main (it was bought in 1973) went down about 4 years ago and we've had trouble finding parts for it. The company is long out of business and Mr. Wilkinson died sometime in the late 80's. It was replaced by an LPB Omni 1000, which is now our main. The old ITA-1000B, now 43 years old, was the station's original transmitter when it went on the air in 1965. It is in good repair and is still in service as our auxiliary rig. While the Omni, with no filaments to light, uses considerably less electricity, the old ITA has a beautiful, warm, all-tube sound. And in a severe thunderstorm, when the solid-state rig is kicked off the air, the ITA just sits there and plays like nothing is happening. It really is an old workhorse!
