Presenting the documentation for the F5m appearing shortly in the store.
The Essentials kit consists of the Jfets and Mosfets plus two channels of pc board and 1 power supply pc board.
The Completion kit is everything else except chassis, power transformer, rear panel connectors/switch/ac inlet.
The kit is designed around several chassis available in the store, but is fairly agnostic.
Attached is the article I wrote for this project, and this is the support thread.
2/11/2024 After testing by member 6L6, I revised the power supply layout and made an additional
note about the power supply thermistors with higher output stage biasing. The revised article is labeled
R1, and both are attached below.
Update Alert: It turns out that the insulators we bought were not very insular. Not a disaster in general
but a problem if your heat sinks are bare metal. Different pads are available for this.
See the details in post 1,003 of this thread.
Also note 4/21/2024 revision of the power supply board.
