hey, don't mention it. i should be thanking u anyway. btw, i've changed the whole circuit and atlast get the desired output. alhamdulillah.

later i upload the pspice simulation. actually i just play around with the resistor at base. and it seems like the resistors at emitter plays no role at all. i wonder why? it suppose to equate as a Thevenin equivalant but nothing seems to differ when i plug in/plug it out from the board.

neways , nice knowing ya. i'm going to jalan pasar today. getting transformer and maybe if i'm free this weekend, we can meetup for the voltage regulator tutors (sila tunjuk ajar). laugh.gif notworthy.gif

anyway luckily my lab instructor didnt check the VBE or base voltage. coz it's roughly around 0.58V for first stage and 0.705V for second stage amplification. LOL. one is low the other is too high. i still not satisfied of why i get like dat. if only i can buy myself a function generator , oscilloscope and a dual voltage DC source. sheeesh alakazaaammmm...KAPOOF, may money grow on trees!!!! laugh.gif

I m baffled too la. We have to look at it again.
Actually you can build a function generator (DIY).. oscilloscope, there is a freeware program that used your soundcard for input.. dual voltage DC source.. well this one also can DIY mah! biggrin.gif

PS.. Tell me where this money tree is growing k...  tongue.gif

hi guys,an old e&e student here. can i join u guys 4 the so called diy n modding stuff. study e&e but my tech skill are low.

blown my 20 bux soldering iron last 2 most working on a project for my electronic manufacturing corse. my college lab tech adviseson buying a high power/wattae iron for soldering. whats r u guys opinion on this.
*
same. i'm an e&e student too. start from zero. still in the process of learning. but i got some theoretical knowledge as a backup.

empire23's hakko 951 soldering station with multiple tips will cost around rm1.3k at melectron jalan pasar. bargain for cheaper price if paying with cash.

I really hate removing SOIC. Impossible for me.
I tried for almost an hour without success. In the end, I just get a screwdriver and peel all the legs broken, then use a sucker to suck out everything thats left. Soldering it is a lot easier by using blue tag to make it stick to the board and then solder one side, remove tag and solder the other end.

*Shit, Im Kapitan anyway... loggin from my bro pc...

aah la.. if theres a custom card board with holes of the size of the connection at the pcb, my soldering work shall be more neat. lol.

Is this thread dead or what? biggrin.gif
Just a 'survey' here.
How many newbies here interested to build a portable headphone amp that cost around RM20?Maybe less. It'll be a value for money/highest bang for buck device.. tongue.gif
Just to help spread the hobby..
