Hi Stephen,

Sorry we do not have info about the rewinding service.

We have a torodial transformer for a massage chair that is non working. Is there a service that rewinds single transformers for $100 or less. Thanks.

Sir Jestine,
This is very interesting and valuable topic in tranformer's Era.
Actually, Topic already given astonish informations about the toroidal transformer. Despite, above transformer quality is more useful and safe in order to accuracy and precision measures with respect to E-I Core transformer.
for example: Toroidal transformer is mostly used in Low wattage servo AVR stabilizer System. Because, its accuracy depends on precision control 380 degrees movement and rotation.

To Sum UP, Servo AVR (Toroidal transformer based) is safe and accurate solution for home electrical equipments with respect to E-I, Type devices.Also, its upto the user what they wants and its need with in the budget.

thanks you
Amir Mukhtar

HI Francesco,

You can check the transformer by measuring the input and output resistance. If there is ac input and no ac output then you know the transformer have problem. If you have the blue ring tester then you can check the winding to see if it is shorted or not. Voltage testing is the best.

Dear Mr. Jestine, I was approaching your ebooks and I will buy them soon because I'm very interested in them.

I would like to know how can I check a Toroidal transformer, please.

I just ordered a Peak Atlas LCR (that can measure Inductance and passive components), but I don't know if I need a Blue Ring Tester too.

May you help me to choose the right tools, please?

Many thanks
Best Regards
Francesco
