France agrees with me. Go to http://www.franceformer.com/faqdetail.asp?FAQDataDis_Action=Find('FAQNumber','66')&FAQDataDis_Position=FIL%3AFAQType+%3D+%27Neon+Transformers%27ORD%3AABS%3A15KEY%3A66PAR%3A and it says: 3.015 What is underloading and what effect does it have on a transformers life? Underloading, or connecting less tubing than recommended, forces the transformer to supply more tube current than normal, resulting in increased wire loss and higher operating temperatures in the transformer. This reduces the life of the transformer. That is one of the places where I got my information from in the first place.
