Well, I wasn't to impressed with my crappy Tungsram AC128's and AC176's so I settled with a couple of russian MP20B for Q1 hfe 80 and GT402B for Q2 with Hfe 105. I haven't decided which NPN Germ to use. I have a MP38A in the socket right now with a Hfe of 95 and it sounds good if a bit dark. My higher gain GT404's leaks to much to function properly in this curcuit.
As for the silicon side, Dino T have already done all the footwork over at DIYSB and I followed his suggestions as three 2N2222's didn't really cut the mustard.. A low gain NPN with a Hfe of around 65 for Q4. I went with a metal can 2N2369A. Metal can 2N2222A for Q5 with Hfe 200 and another 2N2222A for Q6 with Hfe 245.
And to complete the mojo puzzle I wen't with a 2N2428 for Q7 but any medium gain NPN silicon
can be used here.
