SE EL 34 DIY output transformer 

:)

Tylko weź oblicz te przełożenia do tych kilku standardowych zębatek ;)

Magic :)

Będą jeszcze pomiary :) ale czekam na oporniki katodowe :). A po pomiarach chyba trzeba dać film jak to gra :)

No manual for winding machine :) - I calculated gear ratio for output transformer for this amplifier output parameters.

Sorry I don't have any manual, it was build from my imagination :).

No - it was calculated for this transformer :)

Hello - what are You talking about - what result ?

Maybe, I have to check my computer :)

@@trzystaes I guess you don't have them :')

Yes steel E-I shapes for typical 50 Hz power transformer

@@trzystaes Thank you sir. i hope it can give me 20hz. it's hard to get fancy steel here. only H20 is available, even H14 is too hard, impossible to get M6 or better.

Yes :) 100 % - my project

@@trzystaes Would love to see its blueprint if you have it 🙏🏻

@@smartrajful no manual :(

@@trzystaes 😔

Tube EL 34 core size EI 84 E&I core 84 not EL 84 but EI 84

Tube EL 34 trafo size EI 84 - clear ???

What do You mean - laminations ? Core or paper between layers ?

@@trzystaes I mean the core. I did a search and it turned out that it's almost impossible to buy a regular electrical steel core alone.

I bought this EI 84 0,33 mm trafo steel in my country - It cost a few $ for 1 kg :).

Can you tell, where in Poland is possible to by EI84 trafo steel, do they sell online? Do yo use 0,33mm or 0,5mm? I am interest to make my own transformers too. Where you get thees transformer end bells (decorative metal pieces for covering bobin) btw, your lego mashine is awesome :)@@trzystaes

10 Hz - 30 kHz (-3 dB) for full power 7,2 W with cost about $15 for one trafo - for me ideal balance between cost&quality
