Before connecting, use silicone grease under the transistors. The maximum voltage is 12 V. The transistors operate in class A. At 12 V, the current is 0.45 A. 1.25 W output power, 27 dB power gain at f = 400 MHz.It will be good as a class B symmetric output stage driver. Delivery time was 60 days.

Werkt goed bij een voedingsspanning niet hoger dan 10 volt 100ma. Ingebouwd in een metalen behuizing, met een opening waar de koelvinnen doorheen steken.

Powered up on 15.03 VDC as specified and transmitted. It fried in 10 seconds. I suggest using only 12.0 VDC NO MORE. Awaiting new order.

As previous comments. Max 12VDC no more. With 12VDC vertical alignment and addition ventilator are necessary.

Good working ampifier with low noise level. For continuous operation I recommend additional air cooling.
