Product details:
T2500 static working point and power supply are both in pure Class A mode.
The electronic tube is set with a soft start, and the filament slowly heats up and heats up when turned on. After 20 seconds of temperature rise, the high-voltage power supply is turned on, effectively extending the lifespan of the electronic tube.
The preamp comes with protective measures such as output delay and instantaneous disconnection when turned off, so switching on and off has no impact on the power amplifier.
E88CC * 2+ECC82 * 2 form a constant current sinks architecture, with good frequency response, low output impedance, and strong load capacity.
The layout is reasonable, and the power supply and signal amplification parts are separated by heat sinks to reduce interference, improve signal purity and signal-to-noise ratio.
Shielded Nippon Steel pure copper Toroidal transformer provides separation and reduces electromagnetic interference.
Japanese ALPS motor remote control volume potentiometer with high accuracy.
All aluminum alloy remote control, with good touch and high grade.
