@enthalpy, glad to help.
@lefty, I have to laugh, I don't have a lot of use for Radio Schlock in general, but the two things that they were my standard supplier for were project boxes and filament transformers. I still have a bunch around that are probably decades old. Doesn't look like they've changed much. I liked the small 300mA models.
LOL, but now they sell Arduinos and stuff, so they have improved a little in my book. I did a quick search on small filament transformers and nobody came even close to the price they want for their 300ma one. They probably aren't aware that they are sitting on the last large quantity inventory in existence.
