Thanks for clarifying, didn't know that you made the board . I'm not really good at electronics, but I will probably ask a friend to help me with this mod. Purer signal is very welcomed for any Stax setup. . I tried your suggestions to switch the L and R and the problem is now gone. No more of out of phase soundstage and the problem with fuzzy highs is gone. My Lambda sounds real nice now. Thanks.
Hi everyone, I just bought a normal bias SRD-7 modified into pro bias. It sounds a bit strange through the Lambda. The sound is a seemingly out of phase and clipped on the highest frequency. Tried different amps, and the results are similar. The mod board has a head-case logo on it and labeled Mjolnir Audio. I suspect it was wired and soldered incorrectly by the previous owner as it is not wired according to the color code for the R-channel input. Here is the picture of the insides: Could anybody who has experience with this board confirm if it is indeed wired incorrectly? Many thanks in advance.
