Not balancing the magnetomotive forces is never a good idea, especially, when designing an amplifier's mains power transformer. If the primary is not distributed on the two sides of the core, this will lead to a lot of magnetic leakages, which link with the amplifier's highly sensitive input circuitry. To minimize magnetic flux leakages, you have to avoid sharp edges in the design of the iron core, and to distribute all coils evenly over the entire magnetic core. I strongly suggest readers to consider these before attempting to build a transformer like this. Magnetic leakages lead to very hard to rectify hum issues that ruin an amplifier's performance. An alternative way to mimic a toroidal core is to use the stator of a motor. Given a sufficiently thick stator core, one can saw off the inner sides where the stator coils are wound.
Obviously you have used the seond bobbin to hold the core together, you could press holes at the end of I's that would make neat and clean transformer along with mounting nuts and bolts.
The thick wire which you have used here as Secondary is LV which used near to core not outer of the core and like wise the wire you have used as primary is HV so it should be outside by doing this Flux leakage is minimum and TAPPINGS can be taken easily!
Why at the end, when you connected the two coils in series, bulb didn't light up? And if secondary is open, and you connect bulb in series with primary and if bulb lights up, does it mean the primary winding is good or it means it's bad?

You are genius in audio .I wish you for 10m users
world's best video this is your idea very uniqe for india anyway this is thailand elctronics
awesome tutorial, Really helpful for MY DIY PCB Design Projects
All video super bro👍👍👍👍
Great job with all the best information
Obviously you have used the seond bobbin to hold the core together, you could press holes at the end of I's that would make neat and clean transformer along with mounting nuts and bolts.
There will be air gape in between core sheets inside the winding right?!,🤔🤔🤔
Thanks, Very Nice Video
Do you use normal masking tape for winding isolation?
Very nice vdo thanks a lot for good job
Excellent video & description. I need transformer to hook Jbl car 4 channel to home use. Plse suggest which one to buy or diy in india
Two coils good idea. Careful about the polarity of windings.
nice work only one thing is not clear that 50 x 2.625 = 131.25 and not 113.25 but maybe I missed some passage.
Right
How to ampere wire gauge calculation primary and secondary calculation
Ns/NP=Vs/Vp=Ip/Is (n =nuber of turn; v = voltage and I is curent).s and p primary and secondary
You can not be more explicit if you want to share
Great job, my friend! Bravo, my friend!
is it 50v 30A = 1500w x2 ,50v 15a x2?
Dear sir please give me answer. Where you find this core material from? I need this one
India
Es bácano ver tu trabajo y más cuando lo enseñas pasó a pasó me gusta sigue así compañero
Hard Work, good job
The thick wire which you have used here as Secondary is LV which used near to core not outer of the core and like wise the wire you have used as primary is HV so it should be outside by doing this Flux leakage is minimum and TAPPINGS can be taken easily!
can it drive 8000 watts ans 20000 watts amplifier? and whats the details? please show it here 40v,65v,90v,115v in one transformer ?
How did you connect this testing lamp
What is the law that you extracted from verse 42, please answer kindly
Secondary wire gauge?
Buenos videos nomas nunca mencionas el calibre de alambre a usar
Hey broh.. is it important to use plates.... Does iron solid core work??
Does it works for 24v 20a ?

Nice! Can you check what is the efficiency of this transformer? At low power it should not heat up a lot
At low power why would it heat a lot.
It's good for welding set ...not for high end audio devices .... toroidal is best option
Que calibre es el devanado secundario ???
Sir secendary me kitne no wire use kiya he?
sir slicon steel core ka price kya hain
Why at the end, when you connected the two coils in series, bulb didn't light up?
And if secondary is open, and you connect bulb in series with primary and if bulb lights up, does it mean the primary winding is good or it means it's bad?
where do you buy the core?
Gosto muito de ver o calculo de voltagem , wattz e ampere isso é fantastico .
Depois poderiam falar sobre isso por favor em uma aula obrigado.

Instead of two bobbins you could use only one.

cuantos amperes es el devenado secundario?????
Sir how dicit wire gauge to ampere please
This one is easy to construct than toroids
এটা তো ওয়েল্ডিং মেশিনে লাগালো যাবে রে ভাই
এতো বড় ট্রান্সফরমার দিয়ে কি করবো?

Amazing

Secondary wire gauge ko bhi mention karna chahie tha. But very nice and helpful video.👍👌👌👌👌
And how do you get the 30 amps?????
With Caliber 15 you can't
Please make a welding transformer please
4cm x 4cm = 16cm
16 x 16 = 256 watt core
50 x 30 = 1500 watt transformer
Not work rong calculation
kiDz Fun correct
its only delivering one core 250 watts
!!add the transformer power calculation!! (10 x 10=100 cross section aria the rule 42 /100=0.42 per volt turns )
Brilliant broooooooo
