Description

# 200 W mono tube amplifire # Exemple power tube-amplifire based on EL34 power tubes in H bridge configuration. Modular design to be able to use it as Guitar amplifire or as WifFi amplifire simply by changing some components and using an other pre-amp stage. Using régulated 12.6 V (+/- 6.3 V) Filament power supply for nise enhansment. Power rating is an estimate. Usualy 8 EL34 lamps are capable of a bit more.
