Andrews DX-1600 series of linear amplifiers

The DX-1600 is a class AB1 passive grid high power RF amplifier using the Svetlana 4CX-1600B external anode ceramic tetrode valve. This amplifier is a combination of the latest technology, the best components and state of the art circuit design. The result is truly world class.

We are currently not manufacturing these amplifiers and regret that we have no stock of them. We occasionally have good used examples in stock.

The 4CX1600B is an extremely rugged, high gain and highly linear valve made in Russia. These factors made this Svetlana valve and also the GU-91b our first choice for consistent and excellent performance with low drive and high RF output power.

Specifications

  • Frequency range: 1.8 through 29.7Mhz inc. the three WARC bands.
  • Circuit type: Passive grid, Class AB1.
  • Cooling method: Dual speed fan forced air ducting and cooling

  • Input impedance: 50 ohms unbalanced
  • Modes: SSB,CW,AM,FM,RTTY,SSTV
  • Output impedance: 50 ohms unbalanced
  • Plate voltage: 3.2kV approximately
  • Power requirement: AC 240V, 50Hz, 16A max.
  • Power valve: Svetlana 4CX-1600B or GU91b tetrode x 1
  • Protection: Amplified ALC, over grid current alarm, over temperature alarm, soft and stepped AC start-up & AC input safety interlock.
  • RF connectors: Two UHF (SO-239) sockets.
  • RF input: Less than 100W for full RF output.
  • RF output: Approximately 2000W SSB, 1500W CW.
  • Weight: 36Kg approximately
