The back of this one is red ,red, black, silver ,red. Think this may have been doctored at some time. R2= Gold, 3x reds. Im reading this as 2.2 with 5 % . From what i can see, i think someone has had a go. Also diode D1 is cracked in half... wow, think this board needs to be stripped and started again. Could you tell me the voltage rate on these, looking at Farnel for replacements.
