The Aphex 107 used a new(at the time) idea, they called tubessence or RPA (Reflected Plate Amplifier).
Basically its a circuit that operates tubes plate at a constant low DC potential. However they use a current mirror to extract the proper plate current. This way there is very little plate voltage swing, so they can operate from a low DC plate voltage.
This is not extactly a starved plate amp though. Typically a starved plate amp limits the current though a large value dropping ressitor (5-10 meg or so). This causes a big voltage drop at the plate, and little current. The 107 doesn't do that.
This starved plate idea is what you find the Tubedriver distortion pedal....at least the smaller version seen at the link below:
Anyway, they are as Moonbaby said- different.
What you you mainly using it for?
