i received a lot of old stock Juergen Haible pcbs,
its planned to build 2x Frequency Shifter in 2U 19" rack with indcluded 2 LFOs for modulation like my first build.
Further its planned 2x Triple Chorus in 1U 19" Rack or as desktop case like my Haible Krautrockphaser.
I left a old stock Tau Pipe Phaser pcb too, its possible to add this in a 19" 1U Case with the great Triple Chorus too.
