Re: amazingly…cheaper for 4 !!

There were a few times during my 28 years designing medical electronics when I needed custom transformers for my circuits – I took a circuit prototype "breadboard" to a local small company that designed and manufactured inductors and transformers and told them what the inductor had to do in the circuit and let the experts there design them to work in my circuits. I wasn’t going to pretend to be a transformer designer! That strategy worked great!
