Ed, many thanks for that comprehensive answer. All bar one of these devices have that capacitor you describe tucked away in the base. Can't be more than a few tens of pF at most I'd have thought. The sole exception is one with 6 pins instead of 5 for some reason. The 5 pin ones have 3 on one side and 2 on the other and I *believe* the 3 side is input and the 2 pin side is output. Normally only two of the three input pins are used. I think there's an extra inductor in there if you want to use it in which case you connect to the two outer pins. Seems there's a bit more to these trannies than first appears!
