I have a ton of trannies but somehow missed 2N3906
Will a 2N3904 work?
Perhaps a good website for substitutes?
I'm building one of Barrys Emerald Rings....
2n3906 is a PNP transistor.
2n3904 is NPN.
You can sub in a BC557 or similar, just remember to check the pin-out for both 2n3906 and whatever you sub.
2N5087 could also work... but has higher gain.. depends of the purpose.
Thanks..
