Working Great Sound: APPJ PA0901A TUBE AMPLIFIER. In good condition, has a few superficial scratches shown in pictures. Thank you for looking!

GEMTUNE Miniwatt APPJ PA1501A Mini TUbe Amplifier 6AD10. Used for about 2 hours into Tannoy speakers This is an excellent condition lightly used PA1501A amp. The power tubes are GE 6AD10. Pure sounding Class A amp Product description: PA1501A tube amplifier is the first tube amplifier launched in the APPJ workshop in 2015. It is an upgraded product of PA0901A. PA1501A uses imported 6AD10 brand new stock electronic tubes. There are many brands of 6AD10 on the market that can be directly replaced, such as Grants Bradford, Amperex, RCA, Sylvania, Westinghouse, GE, Philco, ITT, Chief, Tung-Sol, CBS, Admiral, Standard , Arcturus, Raytheon, Zalytron, Aladdin, Zenith, Motorola, IEC, Amperex, Mullard, etc. 6AD10 is a late-stage thing in the history of electronic tube development. It is an indirectly heated cathode double pentode-pentode composite tube with excellent performance. We use low-power pentodes for voltage amplification, high-power pentodes for power amplification, and transformer coupling to transmit power. The performance of the amplifier composed of 6AD10 is much better than that of the amplifier composed of 6BM8, ECL805, ECL82, and 6F3. It is manifested in three aspects, noise, frequency response, and power, especially power. The 6AD10 amplifier can output 3.5W, which is 6BM8. ECL805, ECL82, and 6F3 are incomparable, and the sound is better than EL84 and 6V6. Specifications: Tube: 6AD10 Power Output: 3.5W+3.5W @ 8 ohms Frequency Response: 30-40Khz (+-1db) Input Sensitivity: 500mV Signal-to-Noise Ratio: -80dB / 3.5W Residual Noise <0.5mV AC Input AC Voltage: 100-250V AC Power Consumption: 38W Input Impedance: 10K ohms Output Impedance: 8 ohms (Japan Z11-EI48*24 Output Transformers) Dimensions: 160mm (w) x 134mm (d) x 125mm (h) Weight: 2.5kg Input: RCA Jacks Output: Banana Jacks AC: Standard IEC Jack with Fuse protection (2A Fuse)
