[Amps] how to figure out solid state rf bias

[Dan Sawyer]

All,

I have a couple of RF amps pulled from medical equipment. The power 
circuit is straight forward. However I am looking for advice on how to 
figure out the bias circuit. The power transistors are 24 volt. Is there 
a way to safely approach how to establish an input voltage for the bias 
circuit?

Does anyone out there have an example of a circuit diagram for this type 
of amp?

Thanks,
Dan
