arrow Overview

The Kingsley Duke is a combo amp for Jazz guitar players and was inspired by the Gibson GA-50, as used by the famous Jim Hall. The Kingsley Duke uses a cathode-biased output section, with a 5AR4 rectifier tube, two 6L6 output tubes and a 6SN7 phase inverter. The pre-amp uses a single 6SJ7 pentode. The amplifier uses Jensen alnico 12” and 8” speakers in an open back cab.
