    I think I figured it out! The schematic was probably wrong. As you can see, the coupling cap in the second preamp stage is missing. I plugged one in and voila! full-blown gibsonette :)) very nice indeed. Thanks for the inspiration and motivation for this project. I'll post some pics as soon as I can.http://music-electronics-forum.com/attachments/314...

    Hi there! I finished the gibsonette project yesterday. Although it sounds good, it has really low volume. It outputs the same with only one of the 6v6's connected .... has this ever happened to you? I think the tubes are ok, even tried replacing the 12ax7 with a spare one but to no avail. I tried each 6v6 alone and they seem to be working ok as well. Really don't understand why the two 6v6's in paralell arent outputing more....I can't find any mistakes in the circuit.Thanks!

    Thanks a lot! I'm going for a gibsonette build then. I'm not finding the schematics for the parallel version though.
