    Stereo Audio power amplifier 2 x 40W - 80W

    I can use MJ15024 in this configration , they are 250W power transistors , to increase power , beacuse MTP75N06 is not manufactured as well as MTP60N06 THis only Leave BUZ11 and IRF540 , which can be found . but if i use MJ15024 in parallel combination with a good heatsink will it work Can You...

    Stereo Audio power amplifier 2 x 40W - 80W

    But the amplfiers that are in the market , especially Car Audio Amplfiers , are rated 1000W maximum value and 500W x 2 channel RMS IF i use one 250W for the Deck and the other one for the Car . i Will have to use a square wave inverter to produce 300W from a 12V car battery. and a square wave...

    Inverter Circuit 12V DC to 230VAC Sine Wave

    I think just using a simple LC Circuit at the output will be goood .  but the problem will come as the RC circuit produces a sawtooth if a square wave is input . i don't know what happens to a LC Circuit , it would produce a sine wave , but will not be linear

    Convert 0-30V 3A PSU to 5A or more

    BY the way i will try to buy another bigger heatsink , which has four TO-3 Transistors output it is about half the size of the M250 audio Amplfier (250W). It cost's around Rs 100 to 110 . i will take that. But You were saying , that we can use two Output Transistors paralleled ,( i am talking...

    Inverter Circuit 12V DC to 230VAC Sine Wave

    Will a Ferrroresonant Transformer Produce a Sinewave from the Square wave input and one more thing , as shown in figure is it possible to use a simple transformer and then add a capictor at one end with some rating

    Convert 0-30V 3A PSU to 5A or more

    But if i use the 2.2W x 12V fan , the Cooling will increase very well and will increase the thermal resistance

    Convert 0-30V 3A PSU to 5A or more

    Audio Guru , i also have the pic for the heatsink i am planning to use with this powersupply , and i was able to find the power transisitor TIP31A . THis heatsink is as closest i can find on farnell . which has thermal resisitance of 3.3 degrees C/W is this suitable. There is also a picture of...

    Stereo Audio power amplifier 2 x 40W - 80W

    Well Here is another Amplfier i found of 1.5 KW how is this Baby . this can drive upto 1.5KW , this is insanity , but wait just calculate how many batteries  :o Godd Help me . No way , i neeed something like a ferroresonant transformer and a square wave inverter that's allll  ;D Further More...

    Stereo Audio power amplifier 2 x 40W - 80W

    It is getting all in all expensive to build a sine wave inverter. Well Good news i will send some pictures of the heatsink i bought for the M250.

    Stereo Audio power amplifier 2 x 40W - 80W

    IF there are common connections . what will happen parallel voltage is same only current divides , and we have a lot of current no problemooo one car battery is about 55A @ 12V , the one which i have Here is an idea , what do you think

    Stereo Audio power amplifier 2 x 40W - 80W

    so if different channels are used can it produce more power

    Stereo Audio power amplifier 2 x 40W - 80W

    Well Thank God I got the Transistors at a low price , farnell is toooo expensive , i have bargained for Rs 1000 for  8 transistors , one transistors cost Rs 125 which is 1.25 pounds and 0.73 dollars i guess. so really low price. Well BEsides That i also have a 8 transisitor heatsink for only Rs...

    Stereo Audio power amplifier 2 x 40W - 80W

    i Have looked it up in farnell , i found the transistors by searching and selecting my country . My distributer is makkays , so i will be looking to contact makkays . However i glitch that makkays have these transistors  on hand. if not they have to import . But still they cost around 5.5...

    Stereo Audio power amplifier 2 x 40W - 80W

    I Found something else also , the part number in the schematic i posted is MJE15024 and MJE 15025 which is wrong , it should be MJ15024 and MJ15025 , however MJE15030 and MJE15031 are correct numbers

    Stereo Audio power amplifier 2 x 40W - 80W

    i have studyed just now that Class AB is about 79% efficient and Class A transformer coupled have 50% efficiency. However as far as the transformer is concerned , i have decided , a transformer of 2 x 38VAC @ 6A , with 2 x 12VDC @ 1 A for something(the other winding is seperate for from the...
