Supposed to be really good and cheap Post 11 of It would be pretty simple to increase bias some so as to drop the input impedance further. After bypassing the electrolytics in the power supply and adding damping to the chassis I tackled the analog xatasheet.

Post 1 of Post 6 of No, create an account now.

I seem to remember Garbz posted pictures of his Pass D1 variant on here; I forget if he had datashset images though. I really would suggest leaving the transistors alone, especially since you dont have any idea what they do in this circuit.

I performed a similar mod on a Sony DVD player. Here are some pics of the board. Colin cetoole looked the design over and saw some things he didn’t like.

Do you already have an account? I would like to try better transistors.

Sometimes I can hear noise when the player is searching for a track, but the increase in sound quality is worth it. I class-a biased it with two jfets.

This isnt for the schematic I am currently working on, but should be pretty good. Is there somewhere where we can buy PCBs of discrete analog stages? Post 8 of You’ll see the signal from the opamp output will go thru a cap and a resistor or two followed by the muting transistors.

Unfortunately, I can not find the schema. Post 9 of There are improved variations on this, as it was really just posted to get people thinking, but this is probably the simplest it will get while still offering good performance.
