RE: Ready to get my feet wet with OTL magic.... looking for a schemtic or 2

If you want to try something wild and wooly, try Steve (Stephie) Bench's single ended OTL with the output tubes in inverted mode. I provided a link to the Web site for the schematics below. You would have one of the only in the world, and I bet it sounds really great too! I have not built it, but I intend to someday (I have 15 ohm Lowthers, a perfect match). I believe that it only draws about 150 watts per side - a modest energy draw.


You can look on Bench's webpages for more information about how this was pulled together.
