At this point, we have finally been able to release our most anticipated model in this series – the SSS. We have spent the better part of 10 years researching this amplifier, yet the information available was limited and understandably closely guarded. -
Page 3: Quick Setup
In our humble opinion, the result of our labors is truly sublime and an entirely unique circuit compared to our OTS series. Most of all, we hope the SSS fills the gap you have been searching for and becomes an integral part of your tone equation to exhilarate your playing and music. -

In the SSS amplifier, experiment with using the FET mode as a clean boost to overdrive the amp for one of the most pleasing crunch tones you’ll ever hear.
- Page 6 HIGH (FILTER) represents half of one of the most unique (perhaps mystifying) aspects of the SSS amplifier. In the original amplifiers, this represented one of the greatest areas of variablility. In the Ceriatone SSS, the HIGH filter control is a 7-way rotary switch.
- Page 7 PRESENCE adjusts the high frequency response of the power amplifier using negative feedback. Use this control to add sparkle and clarity to your tone. ON / OFF (POWER) two-way toggle switch powers the SSS on and off. With the toggle switch in the UP position, the SSS is ON. In the DOWN position, the SSS is OFF.

- Page 14 - Maximum plate dissipation for 6L6GCs …and now some math. The formula for calculating bias is as follows: In most cases, amplifiers are biased between 50% and 75% dissipation. We bias the SSS to approximately 35mV-40mV reading on a DMM.
- Page 15 That way, a bias current of 35mA measures as 35mV on your DMM. NOTE – Only set your DMM to mV for measuring bias on the SSS amplifiers. Not doing so may damage your DMM. Now that you know how to calculate bias, all you need to do is:...
- Page 16 Even though the bias test points and adjustment are external to reduce risk of electrical shock, all precautions must be taken while biasing. Again, bias at your own risk. Ceriatone Amplification is not responsible for any damages or injuries resulting from user biasing.

Page 17: Frequently Asked Questions
- For best results, an effects loop interface like the C-lator or Klein-ulator should be used with the SSS amplifier. These units prevent impedance mismatching, as well as provide the ability to pad down the volume sent to the effects units hence preventing any overloading. - Page 18 Do I need to use a matched and balanced phase inverter? - It is not necessary. Feel free to experiment with different tubes (of the same type) in your SSS, though! I’ve read that the components used in this type of amplifier are really important. What is inside my SSS?
- Page 19 our vast surplus parts collection in locations they work well and complement the voicing or enhance the performance of the amplifier. I like to use rack-mounted multieffects units. What is the output level straight from the EFFECTS LOOP SEND jack, -10dB or +4dB? - While not exact, -10dB is a better approximation than +4dB.
