    DIY Direct-Drive amp for Estats

    And so begins yet another needlessly complex project. I should disclaim before the talk of how dangerous dealing with multi-kV systems is and how I'll hurt myself that I'm in my last year of an electrical engineering undergrad, so I know how to work with high voltage safely.

    Luxman L-85v Integrated Amplifier

    This is a project I did last year - a mid 70s Luxman L-85v refurbishment with a re-engineered output stage. The output stage PCBs were damaged in the early 1980s I've I had this amp kicking around since then. After 30 years, I eventually decided to try designing and building some replacements...
