Post 4 of Post 12 of Thanks for the tips. Supposed to be really good and cheap Colin datasheft looked the design over and saw some things he didn’t like.


For my DVD player, it wasn’t worth the money to rebuild the entire analog output stage. I posted a thread on this a little while back which 2sf1944 a board layout picture. This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register.

Unfortunately, I can not find datawheet schema. Then I took the output straight off the opamp, thru two huge solen caps, straight to the output jacks, effectively bypassing the stock caps, resistors, and muting transistors. I will post some pictures of the board. Post 15 of Hope will raise sound quality. Post 11 of Post 8 of May 29, at 3: The ones closest to the opamps look like they are the muting transistors.


Sometimes I can hear noise when the player is searching for a track, but the increase in sound quality is worth it. Can somebody give me a hand?

Yes, my password is: Is there somewhere where we can buy PCBs of discrete analog stages? The PCB set is 18 Euro, and he can supply parts as well.

Are there some transistors replacement databases on the web? Some of the variations get quite complex; the one I am working on for my DAC projects currently uses something like 62 parts per single ended channel, so would be in datashret range of parts for differential stereo. May 28, at 6: Leave the transistors alone. Current or voltage output? Post 10 of I would guess at least dqtasheet of them are for output muting.

I performed a similar mod on a Sony DVD player. May 11, at 2: I would definitely recommend getting a schematic if possible before just shotgunning parts out. May 9, at 3: Post 14 of It would be pretty simple to increase bias some so as to drop the input impedance further. Too expensive mod compared to the DAC performance, unless there are some great and cheap good analog stages.


I would like to try better transistors. May 29, at 6: May 29, at 7: Datasheft, there’s always the LC Audio Zapfilter http: You must log in or sign up to reply here. Post 7 of You should be able to easily trace the output RCA back to the opamp. Also, the Pass D1 stage is another one to look at. Share This Page Tweet. This isnt for the schematic I am currently working on, but should be datssheet good.
