The OM Power model OM4001A is an automatic power amplifier, designed for use on all short wave amateur bands from 1.8 to 29.7 MHz (including WARC bands) and all modes. It is equipped with a two pieces of ceramic tetrode FU728F. The advantages of OM4001A: Specification of …

Type: Amateur HF linear amplifier: Frequency range / band(s): 10-160 m + WARC: Output power: AM/FM/RTTY: 2 KW SSB: 4 KW (PEP) CW: 2.5 KW Drive power:

2500 W output in CW and SSB, 2000 W out in RTTY, AM,FM and digital modes. 40 to 60 W drive for full 2,5 KW. Time Owned: more than 12 months. Purchased the OM2500HF to replace an Emtron DX-2SP (great amp) that I recently sold. Ordered through Array Solutions (Jim and the crew there are great). Very reasonable time from order to receipt of amp.

Introduction The OM Power model OM2500HF is a manual tuning, full legal limit amplifier, designed for heavy duty use on all short wave amateur bands from 1.8 to 29.7 MHz (including WARC bands) and all modes with no time limit. It is equipped with one GU84b ceramic tetrode. DO NOT ATTEMPT TO SHORT OR BYPASS safety switch under upper lid! WARNING!

This is our new solid state power amplifier equipped with liquid cooled Freescale LDMOS transistors. It covers VHF amateur bands 144 - 146 MHz with output power up to 1800W for CW and SSB modes. This compact amplifier has 4.3" color touch screen that can be used to control the amplifier and display many operating parameters.

The OM Power model OM2500HF is a manual tuning, full legal limit amplifier, designed for heavy duty use on all short wave amateur bands from 1.8 to 29.7 MHz (including WARC bands) and all modes with no time limit.

In this amplifier a tetrode GU 84b 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 power transformer with an input impedance of 50 Ohms.

Die Hochspannung für die Anode ist aus acht selbstständig gleichgerichteten und gefilterten Quellen 300V/2A zusammengesetzt. Im Hochspannungsstromkeis sind Schutzwiderstände gegen Überlastung eingesetzt. Die Schirmgitterspannung UG2 ist wird durch eine MOSFET-Schaltung mit IRF 830 stabilisiert und liefert eine Spannung von 360V/100mA.
