Output Transformers - AL0S

ALOS = Advance Level O(0) Series Output Transformers
* Improved Performance of Level 0 transformers.
* High cost / performance ratio.
* Standardization for affordability.
* Open frame with solder tags only.
* No customizations entertained.
* H14 EI core for lowering cost.
