About 2SC2071/2SA939 and 2SB649/2SD669
Please tell me, can I replace 2SC2071/2SA939 with 2SB649/2SD669?
Those 2SC2071/2SA939 are working as pre-driver transistors in one old Sansui stereo receiver, and because I cant find it any more for buy (and I have found non-working one 2SC2071 and two 2SA939), I wish to replace all 2SC2071/2SA939 with this Hitachi 2SB649/2SD669. Can I do this, but the most important to me is keeping original Sansui sound. Comments are welcome! Regards! |
