London Power's "Best All-Tube Effects Loop" (BFX): the tube solution for active effects loop requirements
  • tube-buffered input and 'send'
  • tube mixing stage using virtual-earth mixer
  • level controls and jacks for 'send' & 'return'
  • 'series/parallel' switch
  • local decoupling included
  • operates from 160-450Vdc 2mA
  • heaters can be run at 6V 300mA or 12V 150mA
  • PCB & instructions included

Kit form of the "Best All-Tube Effects Loop" from the book The Ultimate Tone. The 'send' is buffered, eliminating problems with long cables to your effects. The return input has enough gain to support pedals used in the loop even if the loop is inserted in a high-level signal point in your system. Quiet! So quiet the loop can be used at the front end of your guitar rig. Use any 12A_7. The whole board + tube (tube not included) can be contained in the chassis.
