About the KT88
The SAC Thailand Glowmaster KT-88 is a true balanced push-pull vacuum tube amplifier designed for audiophile performance. It features specially designed SILK P-545(Fi) or SILK P-4200 balanced output transformers, precision hand-wound with SILK winding technology to minimize loss, improve bandwidth (5-100,000 Hz), reduce distortion, and enhance linearity. The amplifier delivers 65 watts RMS per channel with peak instantaneous power close to 100 watts, operating in class AB1 design. It uses a 520VA special power transformer with high current hi-speed diodes and audiophile-grade Nichicon capacitors for a low-noise, high-current power supply that performs close to regulated supplies but with greater current headroom. The chassis is made from thick anodized aluminum for heat dissipation and RF rejection, complemented by real wooden side bars made from rare Makha hardwood for an elegant look. The amplifier employs point-to-point hand wiring, high-quality Amphenol XLR inputs, gold-plated RCA connectors, and heavy-duty gold-plated binding posts. It has a very wide bandwidth of 100 kHz (-1.25 dB) with very low harmonic distortion and a frequency response linear within 0.1 dB from 20 Hz to 20 kHz. The Glowmaster KT-88 is praised for its high definition sound and robust build quality. Typical power consumption is around 280 watts, with a signal-to-noise ratio of 98 dB and total harmonic distortion of about 1%. The amplifier weighs approximately 28.5 kg and measures 230 mm high, 320 mm wide, and 470 mm deep. It is a premium product with a new price around plus taxes and shipping.
