I need to add another zone to my IR network and was looking for Guy's amplifier circuit, but link to it in the old forum is broken. Any way to fix this, or re-post a working link or the original schematic? ASCII art from those old postings also goofed up, somehow.
Yes, I noticed that those ASCII art schematics (love 'em or hate 'em) don't display correctly with this forum software. On the old one it would force a fixed spacing courier-style font. Looks like we'll need to make true graphic diagrams and link them here. If anyone has a diagram to post, just contact me (see my address in my profile) and I can insert it in your post for you.

Thanks, Guy. I think I had to use your other version with 2 transistors to fix output inversion to talk with my Buffalo connecting block. Do you have that one, too?
