So far I've bought most all my components from Tayda, and although I've heard stories of people receiving fake or bad parts, I've never had any problems... until now.
I recently got some BC549B and BC549C transistors. When in the Fuzz Aldrin--with the BC549Bs, I get a unity sound with fuzz and volume all the way up, and the BC549Cs I get at most a very slight overdrive. No fuzz or volume boost with these.
This doesn't seem right to me, and when using 2n5088 or MPSA18 it does its fuzz thing.
The gain on these BC549s is way off. When I put test the HFE with the Astroai, they measure around 5-10.
Anyone else encounter problems like this?
I wanted to use the BC549Cs because I heard they're good substitutes for BC109C, which is what the pedal originally uses.
Followup Q: if you didn't have BC109C, which would be your best substitute from the options I've got right now, which are MPSA13, MPSA18, 2n5088 and PN2222A?
