Alps SKCL Yellow Sound Test, Review & Specs
Here's the Ultimate Alps SKCL Yellow Switch Sound Test and Review. This vintage linear switch is also called Yellow Alps. I conducted detailed sound tests using the ADK64 keyboard, Zenith Z150 keyboard, and Tofu60 case, comparing it with other Alps switches in a controlled environment to provide a clear understanding of its acoustic profile on a full mechanical keyboard.
