I made an audio amplifier using tba810 ang that is not working . The circuit only works when my hand is touched over the body of the mic . or on the body of the potentiometer . Please suggest me a solution for this . Pier Francis

the low voltage winding is 8 - 0 - 8 and 0 is battery +ve

u are right . I made a mistake by missing one resistors . Do u have any Idea about the winding details Or could i get a new one for that Pier

since it self oscillating it must be the one for oscillating , some say that it is a feedback winding .

i already measured its current . as i said earlier it draws only 700 mA from a 6 volt battery . and the brightness is very good and sufficient . but i dont know the transformer details . thats the problem . i know all the other values .

i'm sorry for that space

this is the ckt i told u , i saw .

but the circuit i saw was bright enough and draws only 700 mA from the 6 volt battery . I think BPL has started one without starter in the tube . how does that work then ? Ive attached an image of the tube . u can have a look at it .

u could try join the orkut and you'll find many .

but will that effect the brightness of the tube ?

no that dosnt work out . i really need it from a 6 volt battery that draws less current . please try to help me cause i am badly in need of it .

that is not a bulb . it is a compact flurocent lamp(tube) with a built in starter . while it starts the lamp flickers about 2 to 3 seconds then goes to steady state

i saw a circuit that has few components and has a 9 watts cfl tube, but the whole circuit pulls only 700mA from a 6volt 4Ah battery . That is why i asked for it . please do help me .

i need help to make a circuit which consumes very less current for lighting up a cfl tube (9watts) with starter from a 6 volt battery . please help me .

I want to develop a Computer CPU cooler Please suggest me which peltier module to use and from where can i get assistance about how to develop the same . Thanks .

I want to learn about the microcontrollers . since i am new which book do you suggest for a beginner . some one told me that " The Microcontroller Idea book " by Jan Axelson is good . Some one told that u need to learn microprossers first . I am totally confused . Please suggest me . Thankyou

please let me know the place on the net where i can get the datasheet of smd resistors and transistors

yes if ur taking the +ve voltage from the transformer o/p put a 1n4007 in reverse and the capacitor in reverse and then put a 7905 to get -ve voltag .

I want to know if SMD resistors and capacitors of 1206 package ca be used in the project . "LED diaplay digital voltmeter " Published in the home page .also can i use 7805 &7905 as to92 instead of to220 Please let me know . I am a bit new to electronics . Thankyou :) ;)
