I need SMT versions of 2n2905 and 2n3053 transistors. Would 2n2222 work for 2n2905? And would both 2n3904 and 2n3906 work as well as 2n3053? Thanks
2N2905 = PNP, Vce=40, Ic=600mA, hFE > 75I need SMT versions of 2N2905 and 2N3053 transistors.

If you look closely, you'll notice that T1 is PNP, T2 is NPN. If they were both hooked up the same way, one of them would not work.It looks to me like the E and C connections to the right trigger may be reversed in the schematic. Try hooking up the right just like you have the left hooked up. John
No, replace the ICM7555 with an LM555.I am using 555 timers form Maxim. They are ICM7555, heres their page on them. I will try the alternate resistors next time I can get to a radioshack.
