I recently acquired a Labophot 2 but the circuit board for the lamp has died. Nikon tells me I need the old style 'large' circuit board. My circuit board is marked HSV-6-30NC and has the electrolytic cans vertically placed on the board not horizontally like the newer 2-piece board. Can someone help me with finding a replacement board?

Microscope stage is dropping down
When lifting the microscope stage with the coarse focus knob, at a certain point it drops down undamped all the way, slamming the condenser into the light source. Does this mean that the focussing mechanism is broken, or is there any way to adjust it to prevent this? Advise this member.
