Each will be taking ~53W so they will get very hot. Try 100W with good ventilation.
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....

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...

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