Ralf's Single Channel

Our good friend Ralf (http://www.ralfschreiber.com/) has shown us his nice new workshop module for making a single channel piezo pre-amp during HOME MADE 2020.

Some discussion on how to use a linear pot that reacts logarithmically by adding / chaning one of the resistors?

Extra Puffer for Batterie and DC-Power supplier

> bei batteriebetrieb noch  100uF-470uF elko als puffer,

> bei netzteilbetrieb  mindesten ein rc glied R10/220uf dazu!

Other Op-Amps for lower supply Voltages

MCP6002, MCP602, TLC272, LMV358, TLV9002

dusjagr's case

reworked by dusjagr Single Channel

  • Minor changes
  • optimized for SMD components
  • mini-Jack and Pot on PCB

Optional changes to some values
