This is the start of the EZ125 project. It is based on a couple of standard circuits, and I used the same design philosophy as the other ‘EZ’ amplifiers, that is, simple PCB construction and an all in one design. The basic idea was to get to a 125 Watt or more power level in a compact space. The basic design of the amp is a quad of KT88’s (Or KT120’s) driven by a cathode follower and a conventional phase inverter and preamp. The design uses all Octal tubes except for the 0B2. The project is pretty much complete, just need to do the write up and add the missing photos to the gallery. The photo gallery has many pictures right now, just not all of them.
Hang in their, it’s close!
