Post 4 of Unfortunately, I can not find the schema. Yes, my password is: If you can etch your own board, or use protoboard, you could 2sd194 some of the stages pretty easily. Post 12 of This isnt for the schematic I dataheet currently working on, but should be pretty good.

May 30, at 6: Post 11 of What I did was to change out the opamp and replaced it with an OPA May 28, at 6: Too expensive mod compared to the DAC performance, unless there are some great and cheap good analog stages. May 29, at 5: Well, there’s always datqsheet LC Audio Zapfilter http: Supposed to be really good and cheap Are there some transistors replacement databases on the web?


Hope will raise sound quality.

Here are some pics of the board. Post 2 of I class-a biased it with two jfets. Post 9 of No, create an account now. Post 1 of It would be much more worthwhile to replace the whole output stage, preferably with a discrete solution.

What DAC is in here? May 11, at 2: By continuing to use this site, you are consenting to our use of cookies. May 9, at 3: Then I took the output straight off the opamp, thru two huge solen datahseet, straight to the output jacks, effectively bypassing the stock caps, resistors, and muting transistors.

I seem to remember Garbz posted pictures of his Pass D1 variant on here; I forget if he had board images though. Thanks for the help.

Post 13 of Sometimes I can hear noise when the player is searching for a track, but the increase in sound quality is worth it. I posted a thread on this a little while back which included a board layout picture. 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 the range of parts for differential stereo. May 11, at 7: To your original question: I would like to try better transistors.

Post 5 of I really would suggest leaving the transistors alone, especially since you dont have any idea what they do in this circuit. Dahasheet 29, at 7: I will post some pictures of the board.
