old midibox plus question

[nogginj]

Hey yall,

the diagram at 'http://www.ucapps.de/tmp/mplus_new_pcb.gif'

has a part on it i have not heard of. it's a three pin piece at the bottom, right to the left of the 74h ic. has numbers 'BC33...' and i cant read the rest. anyone know what this is and what it's for?

i started the midibox about a year and a half ago and am just now pickin it back up to finish after getting the new pcb.

thanks alot!

Hi,

It's a BC337 npn-transistor, in a circuit for adjusting LCD backlight luminance. If you don't have backlight on your LCD, you can just omit it.
