General HD1969, sound quality is recognized by everyone, only the shortcomings of only 10-13W, driving a large speaker a little hard, this version uses Toshiba 15A 2SC5200 drive, the circuit is optimized, the output power and current greatly improved, the output power can be increased to 25W A state
1 using 6-pipe program, including two electronic buffer filter, you can avoid switching on and off when the rumble impact sound,
the speaker is a good protection, 4-tube board, the boot is absolutely flutter a long-term use of damaged speakers.
2 using 4-way HD1969, under normal circumstances, each channel with a minimum of 30000UF capacitor can barely guarantee no noise, because the AC ripple is very large,
6-tube version, as long as the filter with 4700UF capacitor can be (Such as
electronic filter Darlington method, the magnification of 1000, the base connected to the 220U capacitor, the filtering effect is equivalent to the 220,000 micro-filter (220X1000) filtering effect,
therefore, to achieve very quiet, detail, level, 6 tube effect and
cost are better than 4 tubes.
