The Bearcat 412 kit provides (almost) everything you need to build four classic, discrete mic preamps in a 1RU chassis. The kit was designed to be built as a class project for university students, and is as such fairly straightforward. The full kit includes the chassis, front panel, PCBs, pre-assembled GLK255 discrete opamps, components, power supply, and connectors. The builder only needs to source the proper transformers.

Features:

• Accepts transformers from Ed Anderson (ClassicAPI), Sowter, and Cinemag
• 8-segment LED VU meters
• Pre-wired XLR connectors
• Custom chassis with all holes pre-drilled
• Silk screened front panel
• Output attenuator for driving preamps hard
