Is that silver mica caps I can see on your board?

Yep, 500pf and 220pf.

I settled on a BC108 for Q2 (hfe ~ 550) and an AC176 for Q3 ( hfe ~ 100, IL ~ 800uA), the higher gain and high leakage AC176 has much more bite and the fizzle is a little less noticeable. I tried an OC140 and an AC127 and this was the best sounding. I got these trannys from doctor tweek, so if you buy the AC176 don't expect Fuzz Face material, all were high leakage.

You weren't kidding. I just got in the ac176 from ebay, most of them were single digit gain, if they had any gain at all they were over 1ma leakage. What a waste of money.

Yep those things were seriously leaky. I didn't end up using them for anything. That's pretty much 6 bucks down the drain. They sound okay in the Cosmo but I cant think of anything else to use them for. I am done with Tungsram stuff, really inconsistent.
