Thank You By purchasing the Zen Triode amplifier you have illustrated a desire to rise past the normal hi-end hype and own a truly exceptional piece. It is a product based on the old school way of doing things when it was fashionable to push quality to an art form. Your amplifier was hand-built by the very best artisans who have perfected the craft through the experience of building well over one thousand amplifiers, each one at a time.

Introduction and Performance Features Important Information Fuse location / Information 1 The fuse is integrated into the IEC power cord connector at the back of the SE84C. 2 3 4 5 6 Caution: To prevent electrical shock make sure that the AC POWER CORD IS NOT CONNECTED TO THE SE84C when inserting or removing Vacuum Tubes, as there are hazardous voltages present at the pins of the Tube Sockets. When Vacuum Tubes are installed or removed make sure to seat them properly in the tube sockets.
OUTPUT TUBE WARNING The SE84C is designed to use either EL84 output tubes or SV83 output tubes. No adjustments are needed when switching from one to the other. Of the type SV83 tubes carrying the Svetlana name there is one batch known to be questionable and ARE NOT RECOMMENDED for use in this amplifier.
INPUT TUBE INFORMATION WHERE EVERYTHING GOES The SE84C is designed to use your choice of three different input (or signal) tubes. Below are the tube locations, input jack configuration and power switch location. The input switch, one for each channel, changes between direct and variable inputs. It always points to the active jack. For example on the left side of the amp, moving the input switch to the right would select the variable input for that channel.
INTRODUCTION You now own one of the best SET amplifiers in the world! Unlike the stereotypes associated with single ended triode designs, the SE84C has many unique features that set it apart from the rest. It’s point-to-point construction, lack of circuit boards, and signal path consisting of only a single capacitor and two resistors means nothing sold today is more transparent or honest.
DIMENSIONS The SE84C amplifier is 6 inches wide by 11.50 inches deep with a height of 6.5 inches. We recommend keeping a 2 inch spacing on all sides and at least 6 to 10 inches of space above the amplifier. Avoid closed cabinets. The better the ventilation around your amplifier the cooler it will run. PLACEMENT HEAT OUTPUT This is a Class A amplifier where the tubes idle at near full power at 47 miliamps each. It is designed to run at a temperature that humans would perceive as hot.
STEREO / MONAURAL OPERATION HOW TO OPERATE To run the amplifier in Stereo, simply connect the left and right input jacks to your source or preamp and the left and right output binding posts to your speakers. If using the variable inputs, the volume control located at the front of the amplifier will control the output level of both channels at the same time. After finding an appropriate place for the amplifier you can install the tubes and connect the speaker cables.
