The Davoli UP10 EL34 Power Unit is a modular output stage using EL34 output tubes, designed to work in conjunction with Davoli's preamp lineup. The UP10 designation suggests a medium-power configuration, and its use of true EL34 tubes rather than EL504 equivalents gives it a slightly warmer, more British-adjacent character.
