The Ceriatone Overtone Special “183” 100 is a clone of a very unique “D” amplifier that marked the transition from high-plate non-HRM amplifiers to the HRM topology that featured EL34s.

If you’re familiar with the circuit design of “D” amplifiers, you’ll notice how…err…different #183 is.  With it’s EL34 power tubes, lack of negative feedback on V1B, barely-there snubber caps on V2, and other departures...183 gives a glimpse into the tonal evolution of one of the most legendary amp builders.

Tonally, 183 sits somewhere between the fatness of the high-plate Skyline and the clarity and harmonic smear of the HRM.  Yeah, we know how esoteric that sounds.  You’ll understand when you play it.

As with all Ceriatone amplifiers, we’ve obsessed over component selection, and it uses our specially designed, custom transformers for superior reliability, frequency response, and feel.

Note: PPIMV mounted on Front Panel will be either mounted in place of pilot lamp (Marshall styles) or a hole will be drilled (OTS styles).
          PPIMV mounted on Rear Panel will always be in place of a Speaker Output Jack.
