For Q2: You could pick appart the old controller and check if it's mainly the insulation and old capacitors needing replacement. If it's the type of controller I think it is, they are usually fine when rewired and the carbon disk stack is checked (I think they replace them or wipe of each one individually). Unless you replace it with a more modern type pedal they work much the same. I would check if the original could be fixed up fine before I replaced it with something else. That said, the foot controllers with non-carbon resistors tend to be much more accurate when it comes to speed control. I have kept the old bakelite controller on my 201 since I've developed a feel for it and it's the original. I think there is a yahoo group with very good support for wiring schematics.
