I spoke at length with Rudi from Emtron. The new DX-2B utilizes a single 4CX1500B, which has good supply from Chinese sources. He is preparing to also include 6 meters into the new DX-2B, which should compete with the Acom 1000 (HF + 6 Meters), except at the 1500 watt level. Rudi said development of the amplifier could be completed later this summer. 73, Bill/K3XA
