[HCDX] RF Systems DX-One Pro active aerial

["Richard Thomas-WW" <richard.thomas@xxxxxxxxx>]

Can anyone help with a circuit diagram for the above please? I've not been able to get a response from the manufacturer. 

The amplifier has died. I've removed it from the tube and have started to hack away at the copious quantity of epoxy resin surrounding the components on the pcb. Unfortunately, the markings on the power transistor in the final stage have been obliterated. This amplifier is fed with 26 volts, operates in class A and dissipates 4.5 watts - yes it sounds a lot but apparently that's what's needed to achieve the startlingly good 2nd and 3rd order intercept points.

Many thanks,
Richard Thomas
