  • The Encel Stereophonic Amplifier X1212 seems to be the starting product of Encel in 1958. The X1212 features switcheable speaker impedance 8 Ohm / 16 Ohm; Has separate Ceramic / Magnetic cartridge Phono inputs; "Hum bucker" adjustment arrangement for each channel to minimise heater hum; Rumble filter; Selectable Normal / Reverse speaker phase; Stereo headphone output. The owner Roger Brinkman: "I believe this unit to be of Japanese origin (or part thereof) as it has a AC outlet socket stamped AC OUT 100V on the rear panel which has been printed over with "230V", and the power transformer appears typical of Japanese units."

    Some remarks we picked up about this Encel X1212: "Mains transformer directly behind volume and bass knobs spells trouble for hum spread by the metal front panel. See in the later C.S.M. 40 chassis the mains transformer is re-located well back from the front panel and hum sensitive knobs, but is still not ideal like the British QUAD 22, keeping transformers in the QUAD II power amplifier located about 2 ft away from the Control Amplifier with hum virtually nil. In the Australian Encel amplifiers, mains hum ripple could be a slight but annoying aspect of performance. R.S.C. got guitar amplifier hum as low as -60dB on valve chassis like this, but the -70dB QUAD II has no audible hum as valve amplifiers with 'potted' transformers and choke power supplies prevent hum and noise, the windings in a metal can filled with solid wax, sealing the hum in.

    Vintage 1960s EL84 amplifier chassis like the Enclel X1212 have 26dB S/N ratio on paper, looking terrible. But Vintage Audio collectors may use modern higher capacity 100 mfd (uF) smoothing to get ripple noise down. Or they may not mind ripple noise in high sensitivity speakers like EMI 319 as temporarily interested in what other amplifiers sounded like in 1958 and why the British QUAD brand amplifiers were so highly regarded throughout the world. 26dB S/N ratio amplifiers can make an interesting contrast."
