Have you not changed the driver current??? If not your pouring parts into something without any real benifit. Unless you were over driving the existing pair of transistors but otherwise all you are doing is sharing the load which only means you can drive lower ohm loads. Although these output transistors should handle down to a 1ohm load. You would just need thick tracks, a good heat sink and a powerful supply. Can you please explain how you deal with cross over distortion in this amplifier circuit?
Please share speaker protection circuit if you have because it is must for such kind of amplifiers.... Please share the circuit diagram so that we can make it..... Thanks well done
The circuit on the video is incomplete, and resembles a component connection diagram rather than a preferred schematic, yes and you are correct to question the input circuit, it's not correct, and he is using 6 output transistors, which requires a substantial drive circuit, and input stage not shown no feed back , no power supply decoupling, no output compensation circuit nothing...The pcb layout is also critical to keep the thing stable too or it will blow up in smoke. There is not enough information given to build a diy amp.
How does adding more transistors increase the sound? More transistors only increase the current capability of the amplifier. Wouldn't you have to increase the voltage of the power stage to get more watts to the speaker?
Hi nice video bro... But i wonder why you are not using a decent bridge rectifier ic like mic 3510 or 5010 for your power supply...... You are not taking full potential of the transformer you have
Good question, the video is incomplete, incorrect and lacking critical information, I really think he is lacking technical understanding of even some of the basics of electronics. The diodes are far too small for that large transformer, and may eventually fail from the inrush current of the filter capacitors charging alone.
I think more x'sistors add up more efficient , it can withstand lower impedance, but not to increase in wattage, increasing wattage needs higher rails, & amps... tnx..
Easiest would be to increase power supply rails. DC rails. example instead of +40 -0 40 , try +60-0 -60.Of course check all component ratings before increasing.
according to some source, adding more tranny will not increase the wattage or sound, instead by increasing the voltage rail will truthfully increase its output wattage ....
Not quite true - Adding additional output transistors (provided there is enough drive for them from the preceding transistors and enough power available from the supply) will allow more current to flow, and therefore more power into the load.
It will just share the power believe me, make it stable from heat and to drive low impedance load but it will not make the wattage high the wattage remains the same the only way to increase power is by increasing it voltage rails or you can do bridge two audio amps, I searched it through internet, and other audio forums... but its up to you then , I'm just sharing thoughts..
more sound with more transistors ? i dont no ... i maked several amplifier with a couple of darlington tip 142/147 ,one couple capable of 150 watts rms ,i add 2 more couple and i have allways +/- 150 watts ... it change just lower heat of the power transitors . i have made 19 amplifier the smaller is for my computer (2x50 watts) ,the bigger is 2x650 watts using both severals tda 7294 and couples of tip 142/147 . good video after all good job but i wish to understand why more transistor = more sound and why my amplifier 150 w with 3 couples has allways 150 ? (i use a toroidal transformer 2x33volts 500VA )
per transistor can take max 1.5 amp. so if you want to make 1000 watts amp you need 50v*20amp=1000watts. for 20 amp need 14 transistor. if you use 4 transistor using 50v 20amp the transistor will be lost. so use transistor according to your volt and amp. thanks dear.
darlington tip 142/147 is capable of more 10 amp piece ;) i never never burned a darligton of this type with my monster toroidal 1500va 22.5 amp :) ,just for fun last day i maked a realy smal cheap amp with one couple of tip142/147 powered by a monster 1500 va ,just fused in primary with 6amp it's all and ,thrust me ,it work well and make an earthquake in my house haha ;) . i try to make a protection not really for the speakers but for the power transistors because if short circuit the output for half second the darlington go on smoke ....easy to repare for sure but with good protection (relay) it's better ;)
Wow this build is hurting my head.How come he has not been hurt by his builds.Inadiquite rectifier hi amp transformer and wrong gauge wiring complete fire risk.
check the transformer first. if the transformer is out side. or if inside check 5 volt first if 5volt fault then tv can't on. because the 5volt makes switching the power board and the vga board.

How to increase wattage????
Sir how much watts it will produce?
it's depend on your transformer. if you use 35volt and 5 ampere. so, 35X5=175 Watts.
and if i use 35 0 35v 5amp center tepped transformer so what is the output wattages?
