Thanks to the kind and prompt response from Deepak and PICaudio. I already had two sets shipped. (Wow, that was fast! Thanks, Deepak!)

I was late for this for my coming KGSSHV build. (was building Lighter Note attenuator and preamps for my Aleph3) Will someone have extra teflon jack, pins, and PCBs for the jack to share? I would like to get two sets if possible. Thanks!

Could someone post the link for the respective follow-up thread (or open the new thread)? I have not seen any one yet.

The SRM-1 MK2 pp (rev. C, spritzer modded to balanced input) was having bad resistors when I just got it. The bad resistors are those 2.2Mohm (R303 & R304) resistors. After fixing that, I like this SMR-1's sound even better than my new SRM-323S for some music. The bass is tight and impactful and the soundstage is more open. Recently, I changed the two diodes (D301 & D302) in the bias circuit with 1n4007. I also replace other two diodes (D101 & D201) in the L&R channels. I found the SQ actually went down (to my ear). The bass impact was weaker and the soundstage shrank. And the DC output from PSU seems to drop a few volts. Then I put the old D301 & D302 back, the bass impact went back. The bias voltage I measured was about 450V before those 2.2Mohm resistors (as it is shown in the photo). I wonder why those changes and appreciate any suggestion on further improvement.
