About the Apollon Ultra KT120 Mono Blocks
The Tsakiridis Devices Apollon Ultra KT120 mono blocks are high-performance tube amplifiers designed for audiophiles. Each mono block delivers 150 watts into 8 ohms using 8 KT120 power tubes and 4 12AT7 driving tubes arranged in a dual push-pull Class AB1 configuration. The amplifier features handmade multilayer output transformers and a handmade 400W power transformer to ensure excellent soundstage and detail retrieval. It uses high-quality components such as Mundorf EVO signal capacitors, metal film resistors, and gold-plated RCA connectors. The amplifier supports both RCA and pseudo-balanced XLR inputs, with true balanced XLR inputs available on request. The design minimizes electromagnetic interference through twisted pair power cables and careful transformer positioning. Dimensions are approximately 24.5 x 53 x 23 cm, and each unit weighs 22 kg. The Apollon Ultra is handmade in Greece and represents nearly 20 years of development, offering a unique sonic experience with the ability to drive power-hungry loudspeakers effectively.
