I have 22 assorted audio transformers. Some are output, some are interstage, and some are isolation. Most of them are marked so you'll know what they are. I'm guessing that most are in the 1 to 2 watt range. Email for picture of the assortment if you want to see them. All 22 for $43.00 postpaid within the US. Thanks for looking, George W7HDL
