Nice chassis, higly collectable and well worth of a restoration. This kind of radios aren't difficult to restore, provided that one isn't seeking to reach the original factory performance (that wasn't great even then), because the chassis is not ...

To bias the FET properly (make the gate "negative" with respect to the source (or cathode) and thus set the current through the FET to the right level), it is necessary to have a bias network between the source and ground. Biasing is accomplished by simply using a 10K resistor and a bypass 0.001 MFD capacitor.
