Big lot of Korean parts for Sale: $40 Shipped.
Everything in pic included:
All crown parts save the saulabi (non shiny) buttons
The Saulabi buttons can be switched with sanwa microswitches.
The sanwa pcb looking thing (i think it’s from a hori) has omron switches that you can take off on it that might be useful to get a feel you like from the k-sticks. Switching around the micoswitches lends a very different feel to each stick, as well as effecting the diagonal range. This lot should give some freedom to come up with a combination that works well for you.
Buttons are solder on terminals (with 3 terminals, kind of like a cherry microswitch). Buttons do have some solder on them from being previously hooked up.
22 tightening nuts included
Note about the buttons, test to make sure you chose the right two terminals to solder to first! Could be very frustrating to solder up everything then have to redo the half of them.
