Rob Robinette SLO Nakid Micro EF80 preset

Verified · 86/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The SLO-Nakid Micro EF80 is a Rob Robinette DIY amp that puts the Soldano SLO-100's overdrive channel into a Princeton Reverb-size chassis. The same four-12AX7 preamp and long-tail phase inverter drive a pair of EF80 pentodes in push-pull, cutting output to about one watt so the SLO's saturated lead tone is usable at home.
