HF2013DX-A
HF POWER AMPLIFER
CAUTION
Before you turn the amplifier on, at least 2 hours should have expired since
it was brought in and unpacked in the room where it will be used. Pay
particular attention when you move it from a very cold into a very warm place
- condensation is likely and this could result in damage to the high voltage
circuits. In such a case, wait at least 4 hours. A similar effect can occur after
a rapid warming of the operating room (for instance after switching on a
powerful heater).

Page 8: Description Of Hf2013Dx-A Power Amplifier
DESCRIPTION of HF2013DX-A POWER AMPLIFIER In this amplifier a tetrodetubeFU728F (similar to a 4CX1500B)is used in a grounded-cathode circuit (input into control grid). This amplifier achieves excellent linearity by the voltage stabilization of the control grid bias and the screen voltage. The power input is given to the control grid, using a broadband input circuit with an input impedance of 50 Ohms. - Page 9 TOP VIEW OF OPENED HF2013DX-A SIDE VIEW OF OPENED HF2013DX-A HF2013DX-A HF AMPLIFER INSTRUCTION MANUAL Page 9 of 37...

Page 24: Tuning
Width of segment in KHz TUNING The HF2013DX-A amplifier is operated in class AB.Thus it’s possible to obtain a maximum outputpower at an excellent linearity. For this purpose the amplifier has to be tuned very carefully.The operation of a mistuned PA will cause malfunctions;the increase of grid current (the G2 will Alarm) and you will have problems with TVI/RFI. -
Page 25: Tuning Instructions
TUNING THE AMPLIFIER TO AN OUTPUT OF 2000 W PEP HF2013DX-A will tune automatically to the TRX frequency via CAT interface. 1. Reduce the power output of your transceiver to the 0. 2. Switch OPR/STBY to OPRposition – The LCD will display 3. - Page 26 G2 Grid is less than 50mA and IA is less than 1500mA Best practice is to Adjust for Maximum RF output power with minimum current on G2 and IA,such as G2 less than 50mA and IA less than 1500mA.

Page 28: Indication Of Fault Conditions
Should a fault condition appear during the tuning or operation of the amplifier the safetycircuits of HF2013DX-A will react. The amplifier will be turned to STBYmode. After approx. 5seconds the control circuits will switch the amplifier back to OPR. If the fault repeat 3 times, the control circuits will turn the amplifier to STBY. -
