Time to use those 2SB175B transistors I harvested here: viewtopic.php?f=13&t=1019
In case there is interest I'll walk through the entire process including the new approaches (e.g. using this viewtopic.php?f=7&t=1015).
I'll be using PCBs for this batch (and future batches). The old way (viewtopic.php?f=5&t=357&p=2076&hilit=32fz#p2076) is too fiddly. With careful design of the PCB there will be no audible difference.
Here is the updated schematic (right click and "open in new tab"):

It is an excellent fuzz. Excuse my ignorance of schematics, is it simply the switching area that has been revised? Any plans for additional features or controls etc.
Anyway glad you’ve got a project to get your skilled teeth into!

Same as last time. Making some more of the same because I unexpectedly found some more transistors.fuzzbuzzfuzz wrote: ↑Fri Oct 03, 2025 7:01 am
