Hi, just found your project and I believe it is a great job!

Please, I would like to try your project, but am unable to find alternative Aliexpress providers for the following material (because the provider does not deliver to my country) and cannot find any other provider for the same specs as:

• 10 x Zinc Oxide Varistor 250VAC 60J 2500A 10mm
  Please, could you provide different providers to choose from or the specs to look for them?
  Thank you very much and keep up the good work!
