RM ITALY HLA300V PLUS HF linear amplifier 250W ventilator.
It is specifically recommended for use only with transceivers up to 15W (e.g. FT-817/818, SUNSDR2 QRP and PRO, or handheld transceivers).
- protection against reverse polarity, excessive temperature and excessive input power and excessive R.O.S.
- PPTT connector
- output power indicator
- 6 output low-pass filters can be entered manually or controlled by microprocessor
- multi-speed forced ventilation.
RM ITALY HLA300V PLUS HF linear amplifier specifications:

Note: Unfortunately the HLA series amplifiers were not originally designed for high speed CW operation. The problem is due to the fact that the bias is switched on with incoming RF and there is a rise time of about 25ms. However with a small modification this can be reduced quite effectively. Ask us a quotation for this modification!
Warranty: The unit is covered by a two-year manufacturer's warranty, except for end transistors, if failure is due to causes such as: indirect or secondary effects of lightning, overheating, poor ventilation, exceeding specifications such as: overvoltage, high drive power, poor antenna SWR or antenna breakage. To avoid controversy, it is important to note that end transistors are not usually destroyed by other causes. By ordering you accept these warranty conditions, if not, we recommend not to order the device.
It is not recommended for old model FT-897 because of the transistors in the radio power control circuit.
