Load both windings to deliver 2.4Aac + 2.4Aac into 9r17 + 9r17 and check how hot it gets after 30minutes.
22Vac+22Vac @ 2.4Aac+2.4Aac is equivalent to an output rating of 105.6VA
Thanks Andrew. How many watts would I need for those resistors?
Each will be taking ~53W so they will get very hot. Try 100W with good ventilation.Thanks Andrew. How many watts would I need for those resistors?
Tony's Line conditioner finished.....230V primary to 230 volt secondary
rated for 1500VA, has a low power winding good for about 200 watts
to use on low power such as test equipment....

to all masters
i want to build a traffo for my APEX500 since i cannot find traffo in our area that has correct va rating, since commercial traffo indicates false VA (in our area).
first Q - will 55-0-55 be enough for b500? how many amperes?
all i have found in the market was EI core with CL 1 1/2" and CL-3"
i bought about 1.5"x5" inches coz 3"CL has the height of 6.75"more or less and the price is 300% higher.
may i ask the specs for the primary and secondary windings?
vis-a-vis t/v and primary and secondary turns.
thank
regards...

1.5"x5" inches will give you about 1500 volt amperes
so that 2 x 55 windings will give you 8 amperes....
still good for your intended project....
this as far as i go....
you have to study on your own about the winding details,
enough information are available on the net.....

Thanks sir Tony,

This is so cool! I wish I'd have access to all the materials. Then I'd surely get a winding machine for myself. Making transformers is such a fascinating task. I did a few some decades ago, using a very simple winding jig and after having bought the wires, laminations etc. from companies in my neighbourhood that no longer exist.
Best regards!

thanks, winding traffos is a therapy of sorts for me, helps me relax, and lots of
good ideas comes to mind.......

Hi Tony,
Is there a place where I can purchase reasonable quantities of EI laminations? At this point I dont really care about geographic location, I just need a source that doesnt consist of a shipping pallet .... lol
try edcorusa.com
Hello, this is my first diy transformer I will still immerse in the varnish, thank you Mr. AJT inspires us with your monatges! Congratulations.
