The key difference between the new version and its predecessor is the modified power supply circuit. Now the manufacturer’s engineers used Schottky diodes instead of a kenotron. This is said to significantly improve the reliability of the power supply.

The amplifier uses four 12AX7 tubes , operates in the frequency range from 10 Hz to 100,000 Hz with a signal-to-noise ratio of at least 91 dB. The new TRX-4 has dimensions of 340 x 310 x 185 mm and weighs 10.5 kg.

Upon purchase, users will receive a protective cover and power cable included.
