    Here's an early draft of the SLO-Nakid Micro, the 1 watt version of the SLO-Nakid with Overdrive Channel only and the FX Loop and Switching deleted. It is designed to use a Princeton Reverb chassis. The preamp is still 100% SLO-100 but the power amp was modified to run a single 12AU7 or 12BH7 power tube in true push-pull. The power transformer, power supply and output transformer were changed to suit the 12AU7 power tube. The power tube grid stop and grid leak resistors were rearranged to form an attenuating voltage divider to keep from overwhelming the little power tube. The NFB resistor value was decreased to compensate for the lower output transformer secondary voltage. I have not built a prototype yet.

    I added a JCM800 style "Clean" input that bypasses the first gain stage.

    The layout is for a Princeton Reverb chassis. As always, let me know if you have any suggestions or corrections.

    I have been very interested in a Soldano amp, but I don't need 100 watts, and this design may be the ticket. Here is a great idea for my next project! Do you have plans to build this amp yet?
