Use bc337 ( to92 ) or BD135/136 ( to126) instead use bc547, they can load 1000mA. ;-)

I was having a look at the "Amplified Ear" project over at ( ) and noticed that 3 of the 4 transistors were bc547 and only one was a bc337.
To this effect I have two questions:
1. AFAIK, the bc337 seems to be a better choice in every way over the bc547, so why did the author u

i would like to know about the bc547 AND bc337A difference between two transistors, can i use it alternatively.
thanks & regards

To drive piezo-buzzers you can use any general purpose NPN transistors ..
Here are some examples:
In general, select one with Vce ≥ 30V and Ic ≥ 100mA ..

I don't check if it's a software problem. But, you use a bc547 transistor, and you don't say anything about what kind of relay you used. BC546/bc547/BC548 transistors gain (hfe) are dependents of how much current drops from collector to emiter. First, base resistor must be lower 1K or less. I recomend that change the transistor to a bc337 is (...)

The BC162 can be replaced with any general purpose NPN transistor:
N100, 2N2222, BC107-8-9, bc547-8-9, 2N3904, bc337 - to name just a few ..

ok for bc 808 but i can'd find BD136 SMD only pth. can i use BCP54 instead of BD136??
i'd like to find a general guide to convert pth transistor into smd. for example how can i change bc547??

Could anyone point me in the direction of a suitable discrete transistor amplifier schematic that would be suitable for amplifying the audio signal from an ipod before it goes into the control pin of a 555. Preferably using bc547, BBC548, BC549, BC557, BC558, BC559, C1815, A1015, BC327 or bc337.....all of which I have plenty
