Aside from Alexan where can I get original ON transistors like MJ15003,MJ15004,MJ15024 and MJ15025.I have tied RS components but lately their price have increased so much.Where did you source the core for the Toroidal Transformer?

Hi Gareth

This is somewhat worrying. As far as Im aware, the company I work for uses quite a lot of components from Communica.

If you still battle to get parts, you can always try to get them as samples. People seem to have varying success with this, but its worth a try. And, at least you will know that ON semi wont send you fake components. Its a service thats worth using, so long as one doesnt abuse it.

Enjoy the long weekend! Youth day I think.
