Re: Dormer & Wadsworth (D&W)
Another possible candidate for having used a D&W front end was the Tripletone FM Mk II of c.1970. In the Gramophone magazine review, it was described as having front end that was completely shielded within a metal box, which suggests a proprietary unit rather than an in-house design. It had 3-gang capacitor tuning with a dual-gate mosfet RF amplifier and bipolar mixer. This description was similar to that of the D&W unit used in the Rogers Ravensbourne.
