In addition, several LEDs indicate the operating status at a glance. For a simple adjustment to the operating frequency, there is a TUNE-Indicator, which indicates the correct tuning.
Extensive protective circuits prevent damage to the OM2000+ event of incorrect operation. Critical parameters such as SWR too high, too high a grid or anode current, mismatch, etc. are constantly monitored. If an error occurs, the PA switches to standby.
A temperature-controlled fan ensures the sufficient cooling of the FU-728F tetrode. If the tube should be changed, the voltage will calibrate automatically. A complicated trimming is not necessary.
The OM2000+ is in this class with only 24kg, the lightest tube amp from commercial production. In addition, the OM2000+ works on 6m with full power.
