yung MJL21194 parehas ang case ng 2sc5200

sa driver walang problema maliban na lang kung sa mas mataas na rail voltage gagamitin

sis pagkakaintindi ko na pagnagpalit u ng o/p tranny e lalakas na ang bass?

edtechph · « **Reply #26 on:** October 12, 2011, 06:42:56 PM »

ah ganun ba? ibig sabihin maganda talaga pang bass yung mjl na transistor thanks.

naku sis hindi po yun ganun, yung mjl na tranny e pwedeng gamitin sa amp na mataas ang rail voltage, halimbawa ang supply ng psu ay nasa -/+ 93vdc nasa 300watts yun.

edtechph · « **Reply #28 on:** October 12, 2011, 06:52:44 PM »

ah ganun ba kasi sabi nila yung mj2955 kahit e design na pang low freq. di bumabayo. kasi yung datasheet ng c5200 at mjl halos parehas yung voltage nya.

BhongTech · « **Reply #29 on:** October 12, 2011, 06:56:22 PM »

mas mataas ang Vceo ng MJL21194 kesa sa C5200.

edtechph · « **Reply #30 on:** October 12, 2011, 06:58:35 PM »

ok po thanks

nakapag canvas na ako sa raon para mapag-ipunan kso nakalimutan ko naman ang presyo.

6 pa lang sir, pioneer circuit(DAW) 8, DXamp 6, DX turbo 4, DX super charge 4, yamaha 6, sansui 4.

Lahat wala akong nakitang pagkakaiba sa tunog.

Roland · « **Reply #36 on:** October 16, 2011, 09:56:28 AM »

1 channel of this amp is quasi while the other is complimentary. quassi uses 2SC2922 6 pairs. the complimentary uses 2SC3264 and 2SA1295.
left and right channel circuit is ready and found to have no error during my contruction im so lucky hehe.
picture wqill be posted soon.
