Buffer With Relay Bypass

Just a quick schematic of a buffer with relay bypass. The relay bypass means that if you lose power, the relay switches back to bypass and you still get a signal like the TC Electronics Bonified Buffer.

  • Based on JHS Little Black Buffer
  • The value of R will depend on what voltage/spec relay you have
  • Most opamps are in 2 in 1 chips. The unused side is wired to prevent noise/oscillations
