I thought I would try this one. I know it is a Fire Bird. The model is F100/BM. Just by the name only, someone else said it was a 2 tube linear capable of around 300 watts. This thing is small.... plus..... this thing has two transistors in it. I can not find any information about this (the /BM) model at all. any attempt to search F100/BM comes back as a F100 and it is a whole different kettle of fish. Has anyone seen one of these?
