YEHUDA MACHLEV, "The Transformer Guy," is a spry and interesting man. It's worth the visit to his "laboratory," more of a bare bones room, lined with shelves spilling with wiring, metal plates and electric cords, just to meet him. Neatly lined up near the front are his creations: transformers for every purpose. He'll ask you what you need to run and prescribe just the right one(s) for you. He stands behind his work, too. And if you're lucky, he'll regale you with his colorful life here since coming from Iraq many decades ago.
Mr. Machlev's office is in a blue warehouse type building at the end of Shatner in Givat Shaul. Go to the top floor and turn right. Always call first to see when he will be there.
