    CONFIGURATION JUMPERS – MODE OF OPERATION: The Model 1 has four groups of jumpers intended for setting a mode of operation – Pentode mode (P), Ultralinear mode (UL) and Triode mode (T). Ultralinear mode can only be used with output transformer that have additional terminal for UL operation. Shorting blocks are inserted vertically so that t he d ...

    CONFIGURATION JUMPERS – NEGATIVE FEEDBACK SELECTION: The Model 1 has optional negative feedback connecti on provided by jumper J161 (J162) – FBK. By moving the shorting block horizontally across the two lower pins, the negative feedback will be engaged. The upper two pins are shorting block holders when feedback is not engaged. By using negativ ...

    CONNECTING POWER: As any other vacuum tube amplifier, Model 1 needs two voltages for proper operation: (1) Plate, or Anode voltage, Va and (2) Heater, or filament voltage Vf. Plate voltage should be brought to the terminal block J80 and filament voltage to J90. Pi cture below shows the layout detail with J80 and J90. Plate voltage (Va) should have ...

    CONNECTING OUTPUT TRANSFORMERS: For basic model, the output transformers should be designed to provide 5k Ω primary resistance. For the full pack, the primar y resistance should have 2.5k Ω rating. Rating of the secondary winding should correspond to the impedance of your speakers (4, 8 or 16 Ω , typically). There are many transformers in the ...

    Again, for best stereo image, they should be connected in phase. The second harmonic distortion is common with single ended amplifiers (i t gives them specific, rich sound), and air transports sound with some degree of the second harmonic distortion too. It is possible to notice change in sound and reduction in distortion just by swapping plus and ...

    UPSIDE - DOWN ASSEMBLY The Model 1 printed circuit board (PCB) was designed with top to bottom symmetry. This symmetry enables building a tube amplifier with “tube audio look”, where tubes are mounted on top of the chassis. All parts, except tube socke ts, can be mounted on the bottom of the board and soldered on the top side (top side is the o ...

    FINAL WORDS Once again, thank you for your purchase. We hope that the Model 1 will give you hours and hours of fun and have you experience a multitude of diffe rent qualities of the “tube sound”. Once you have exhausted all of the options, we hope that you will “retire” the amplifier from your bench into a nice chassis and have it rest on y ...
