This is my spring reverb driver module in Kosmo modular format. It is only one board and components stick out. Please subscribe and like and get notified about upcoming videos on my channel.
I drive an Accutronics 4AB2A1C with 8 ohms input impedance with it. Input coil was grounded to the chassis and I needed to detangle that. PCB and schematics can be downloaded from my GitHub site at https://github.com/polykit/kosmo-spring-reverb-driver
