Ive managed to get the same TIP122 transistors, but the 2N4401 transistors next to them seem to be harder to find Confused
I have some PN100 transistors here, will they do the job ?
Ive looked then up and says they can be used as a replacement: http://www.jaycar.com.au/productView.asp?ID=ZT2283
The PN100 has a slightly lower collector current (500mA as opposed to 600mA for the 2N4401) but slightly higher voltage ratings so it should work ok.
