    The AC FUSED INPUT socket (TYPE IEC Grounded) is a required connection for operating your KITCHEN SINK 6VEL at 120V (standard USA household electrical power). The MAINS FUSE requires a 2.5 AMP slow blow fuse. This fuse protects your amplifier from voltage peaks from your power outlet.
  • Page 10 • Always operate your amplifier with the proper impedance output that matches your speaker cabinet(s). • In all cases, always use a good quality heavy gauge speaker cable (not a shielded instrument cable) to connect your KITCHEN SINK 6VEL to the speaker cabinet(s).
  • Page 11 Fortunately, most guitar speakers roll off the harsh higher frequencies that exist beyond 5 - 8 kHz. The Kitchen Sink 6VEL features a pleasing circuit that replicates the type of high frequency roll off you’d expect from a high quality mic’d speaker cabinet. It’s not invasive, it’s voiced ‘just right’ leaving your downstream audio devices, such as digital multi-effects and power amplifiers, to only receive useable signal and not the ‘ratty/fizzy’...

  • Page 15 Back Panel: Power Tube Biasing CAUTION: NEVER touch hot tubes!!! Temperatures can exceed 500˚F and cause severe burns! CAUTION: Read all of the information and procedures in this section before attempting to modify the factory bias settings of your amplifier. Power Tube Bias Adjustment Control (32) Controls the amount of negative DC bias voltage being fed into both output tube input grids.
  • Page 16 DO NOT attempt to load a rectifier tube in a power socket and vice-versa!!! The Kitchen Sink 6VEL has a logical tube layout with the audio and power tubes located in a cluster near the back corner (see page 19). The rectifier tube is isolated and located in a corner on the opposite end of the chassis.
  • Page 17 Proper Power & Rectifier Tube Use: CAUTION (once again): NEVER touch hot tubes!!! Temperatures can exceed 500˚F and cause severe burns! Your amplifier ships with the bias settings optimized for maximum flexibility and safety. During QC and final testing, the bias is set maximum safe power dissipation (approximately 60% of a given tube’s performance rating).
