Regrettably, after 10 years, I need to decommission these amplifiers. They are quite heavy, weighing at least 130 lbs each, and as I turn 65 this year, I recognize the need to transition to lighter options. In hindsight, I should have constructed them using four separate chassis, as the design essentially combines two amplifiers into one; a 300b driving the GM70 into A2. I'm weighing the options of selling them as they are or disassembling them. I may consider building a simpler two-stage, lower voltage version, which could reduce the weight by 30-40 lbs. I initially built these amplifiers for convenience, allowing me to move them between my main system and my office system, where additional power is required. The numerous chokes included in this design contribute to its weight, and I might explore Kevin Kennedy's lighter version for use with my main horn system, as I do appreciate having extra power available when needed.
The Monolith Magnetics iron is probably worth more than I can sell these for so I'm considering just taking them apart.
Am I crazy?
