Line Preamp, OPT based, Siemens C3M tube
Simple line preamp with Siemens C3m (Deutsche Post) pentode in triode mode.
Special is the shunt PSU, where MosFets are current-sourcing neon stabilization OA) tubes actually feeding the amp stage.
OPT's are Tango, tantalum resistors and cabling AudioNote Vx, Yamamoto teflon sockets ans Siemens gold contact vacuum input relays. Input attenuator Acoustic Dimension.
