1 pair NPN C5200-JLH1969 single-ended Class A back-end finished boards
Description:
The default setting of this cost board is 1A quiescent current at 21VDC
PCB size: 75X50X1.6MM FR4 sheet, 1OZ copper, push tin.
1, mono structure, convenient for players to use the left and right cooling chassis installation, in order to get better heat dissipation, if the optional HPOO power supply ZERO-ZONE specially made for this purpose, completely easy to get a double single independent channel, the physical 100% separation of the left and right.
2, considering only to do the post-amplifier, this version does not add to the increase in electronic filtering, can strengthen the dynamic.
3, input coupling capacitor directly on the Nichicon MUSE BP 47UF large coupling capacity.
4、The output coupling capacitor is directly on the Nichicon KG II gear 3300UF, the capacitor can perfectly match with the input capacitor.
5、In order to make it easier to listen to the ear, the feedback resistor is changed to AB carbon film, and low R value AB carbon film is also added to the input stage.
6, the input level transistor matching is very important, we prefer Toshiba A970
7, the version of the power tube (end tube) for the Japanese Toshiba C5200
Package:
1 pair of C5200-JLH1969 single-ended Class A rear stage finished board.
