  • Page 2: Table Of Contents

    British series with the HRP series of versatile, yet classically voiced amplifiers. We are excited to offer a unique take on these essential tones with our lower powered SON OF YETI 20W amplifier. To do this, we started with our Yeti circuit, and then massaged the sweet tone of 6V6s into the power section.

    2) QUICK SETUP (for instant gratification) 1) Plug your guitar using a 1/4” instrument cable into the INPUT on the far left of the front panel 2) Plug a suitable power cable from the SOY’s rear panel MAINS cable inlet to your wall power receptacle 3) Plug the SOY into your speaker cabinet using 1/4”...

    3) FRONT PANEL CONTROLS From left to right: 1) INPUT ¼” instrument jack 2) GAIN 1 control with BRITE 1 3-way toggle switch 3) GAIN 2 control with BRITE 2 3-way toggle switch 4) MASTER control with ERA 3-way toggle switch 5) TREBLE control 6) MIDDLE control 7) BASS control...
  • Page 5 “saturation” control that will impact pick attack, compression, and feel. Depending on the BRITE 2 setting, you can also use this to shape the high and low frequency response of your Son of Yeti. BRITE 2 is a high-frequency boost that can be used to add sparkle and gain to your tone. In the middle position, BRITE 2 is defeated.
  • Page 6 NOTE - Just like the original “Jose mods”, these different modes will impact the taper response of the MASTER control. In other words, some settings might seem louder than others. In reality, equal volumes are happening sooner or later on the control.

    4) REAR PANEL CONTROLS From left to right: 1) A.C. MAINS IEC cable inlet 2) MAINS FUSE 2A slow blow fuse 3) HT FUSE 0.5A slow blow fuse 4) COM multimeter probe jacks (SEE PAGE 10 FOR EXPLANATION) 5) BIAS multimeter probe jacks (SEE PAGE 10 FOR EXPLANATION) 6) SPEAKERS MAIN 1/4”...
  • Page 8 A.C. MAINS IEC cable inlet – plug a suitable IEC power cable into this inlet to power your amplifier MAINS FUSE 2A slow-blow fuse – used to protect your amplifier from voltage spikes or excessive current draw. Replace only when necessary. HT FUSE 0.5A slow-blow fuse –...
  • Page 9 PUSSY TRIMMER allows you to further fine tune the gain and saturation of the Son of Yeti. Turning this control down can reduce the possible saturation and gain. We recommend turning this up to about 2:00 for the standard gain and response. If it’s too much and too hard to control, you can reign things in by turning the PUSSY TRIMMER down.

    5) TUBE COMPLIMENT AND BIAS ADJUSTMENT From left to right: V1 – 12AX7/ECC83 (stages 1 and 2) V2 – 12AX7/ECC83 (stage 3 and tonestack cathode follower) V3 – 12AX7/ECC83 (phase inverter for power amplifier) V4 – 6V6 V5 – 6V6 BIAS ADJUSTMENT CONTROL IS INDICATED BY THE RED ARROW...
  • Page 11 3) Plug the black probe tip into the COM multimeter jack on the rear of the Son of Yeti. 4) Plug the red probe tip into the top BIAS multimeter jack on the rear of the Son of Yeti. This measures bias for the 6V6 closest to V3.
  • Page 12 DMM. NOTE – Only set your DMM to mV for measuring bias on the Son of Yeti. Not doing so may damage your DMM. Now that you know how to calculate bias, all you need to do is:...
  • Page 13 Biasing should only be done on a clean workbench with no distractions. Do not wear loose clothing or any jewelry. Take your time, and think carefully before each step. Again, bias at your own risk. Ceriatone Amplification is not responsible for any damages or injuries resulting from user biasing.
  • Page 14: Frequently Asked Questions

    - For best results, an effects loop interface like the C-lator or Klein-ulator should be used with the Son of Yeti amplifiers. These units prevent impedance mismatching, as well as provide the ability to pad down the...
  • Page 15 - Although you can try 12AT7s, 12AU7s, 5751s without any harm, the design is optimized for 12AX7s, and are therefore the only recommended tube in the preamp positions. Usage of other power tubes is not recommended for the Son of Yeti 20W. What settings do you recommend?
  • Page 16 Yeah, I read that already. I love ‘80s hair metal. Can this amp do that? - Hell yeah! Put the GAIN controls at 12:00, both BRIGHT switches to the left. Select ERA in the right (‘80s) position. Turn the MASTER up to about 1:00. Turn MIDRANGE all the way up, start with BASS around 11:00, TREBLE around 2:00.
  • Page 17 I’ve read that the components used in this type of amplifier are really important. What is inside my Son of Yeti? - We use a combination of parts custom-made for us to our specifications (power transformer, output transformer, choke, high-temperature / low-ESR electrolytic capacitors) and those used in our British series (1/2W carbon composition resistors, 1W carbon film resistors, TAD Mustard capacitors, high-voltage silver mica capacitors, Belton tube sockets, and Alpha potentiometers, Cliff jacks).
