First time poster here. I have two 125 mk2's: one seems to be an early version with the bulb on the other side of the circuit board and the latter has the dedicated bulb housing on the side with the variable resistor.
Both of these 125's have the same problem: they stay at one speed, the incorrect speed, and they cannot be changed. I even tried moving the variable resistors and no luck. One worked fine before and then this issue. Both of the bulbs seem very dim.
Does anyone know what is the problem and how to solve?
Thanks, love the site!!!!
