Introduction:The JLH1969 circuit is very famous. It is a circuit familiar to old enthusiasts and novices want to play.However, most kits are limited by materials, from low to expensive, and important components also use non-audio output capacitors, which makes more players do not know how to choose. In turn, more players have spent a lot of energy onJLH1969, but they have come to the conclusion that there is no dynamic, no low frequency, and the overall experience is to hear "sound."

Before investing in this version, we communicated with older audio enthusiasts and gained better experience. JLH1969 can be dynamic and have low frequency flexibility. The focus is on the school sounds. After some discussion, we finallyselected the BR program.

 

PNP BR JLH1969 Version highlights:

1, Mono structure, Use both sides of the heat sink to cool, about 100% separation on the physical object.

2, Input coupling capacitor Nichicon MUSE BP 47uF large coupling capacitance,Output coupling capacitor Panasonic 3300uF.

3, Use CRC array filter circuit, the total amount of filtering up to 68000uF per channel.

4, Feedback and bootstrap capacitors use ELNA CERAFINE. For dynamics and strength, these two capacitors must be on ELNA CERAFINE.

5, In order to make the sense of hearing easier to enter the ear, the feedback resistor is changed to AB carbon film, and a low R value AB carbon film is also added to the input stage.

6, Input-level triode matching is very important, we prefer Toshiba C2240.

7, Power transistor uses the brand new original SANKEN A1216.

8, Customized pure copper EI fully shielded transformer with strong anti-interference ability.

9, Full aluminum chassis With both sides heat sink, nice appearance and good cooling.
