Hello, I would like to know which type of thermoionical valve is a component of Technics CH550. This is because I have been told that the brightness of the display letters and numbers depends on the efficiency of the thermoionical valve.
Actually, my very old model of TECHNICS hi-fi (DVD, CASSETTE, AMPLIFIER, TUNER) is still working very well, but the display is not easily readable.
Thanks and regars,
GPV
