PA1501A tube amp is the latest tube amp from APPJ in 2015. It's upgraded version of PA0901A.
PA1501A using imported tube 6AD10, there are many other tubes can instead 6AD10 on the market, 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 and so on.
6AD10 is relatively late in the history of the tube thing, is indirectly heated cathode pole double five - five poles composite pipe, the performance is very good.
We use them as a small power pentode voltage amplification, power pentode as power amplifier, power transformer coupled input Chu.
6AD10 composed of amplifier performance is much better than the amplifier performance with 6BM8, ECL805, ECL82,6F3 composed in three aspects, noise, frequency response, and power, especially power, 6AD10 Chu 3.5W amplifier output is 6BM8, ECL805, sounds nice ECL82,6F3 can not compare more than EL84 and 6V6.
