Commentary
With the circuit design of No26L as it is, this is a special edition model control amplifier that uses a Teflon printed circuit board for the first time in audio equipment.
Problems caused by printed circuit boards such as mutual interference between wiring patterns, which could not be overcome by the glass epoxy board FR4 adopted in No26L, are eliminated as much as possible by the Teflon board.
In addition, because the Teflon substrate is moderately soft, vibration of the substrate itself and parts is less likely to occur, resulting in higher quality.
The internal configuration is a unique dual monaural configuration with the same circuit design and parts as the No26L. It is equipped with two pure A class monaural preamplifiers of complete discrete specification.
In addition, the switch contact part, which has been a bottleneck for the pursuit of sound quality, is limited to 2 places at the maximum between all inputs including the phono input and the pre-output. It also adopts a high-precision relay control using a unique matrix method.
The power supply section PLS-226L is equipped with a toroidal transformer with excellent regulation and less unnecessary vibration and less leakage flux in each channel. In addition, high-quality parts such as high-grade condenser of 6,800 μ Fx4 are introduced to realize clean power supply without noise and ripple.
Equipped with an absolute phase control switch that can invert the phase by 180 °.
There were models with balanced input card, MM phono card and MC phono card.
Also, there were various upgrades such as upgrading of each card and installing an external phono amplifier.
