    Quote:   Congrats for achieving that! Still have to find the time to modify mine for balanced and upgrade some of the other parts. BTW: I fitted mine with one normal bias socket so I can use normal and pro bias phones...

    Quote: Then why not try a SRM-T1 and cut out the tube stage? In my experience, if the phone is not too hard to drive, like sigma pro or omega(2) etc., (and lambda's in general arent that hard to drive), the T1 beats the SRM-1/Mk2 by a fair margin. Unfortunately, I do not owm Lambda...

    Have you tried to first get V_R+/G or V_R-/G to 0V DC and then adjust V_R+/R- for 0 DC? In other words: if there is no offset pot setting at which V_R+/G and V_R-/G is lower than 48V DC, then I assume that something is out of specs. BTW: did you close the volume pot to zero?

    Quote: I remember I had the same experience when I adjusted mine. It seemed to me that balance and offset markings were switched on the PCB. If you adjust offset with the one pot and balance with the other and repeat measurements a few times (alternated), it should be possible to get...

    I have no Lambda pro headphones, but with Sigma pro the amp sounds fine to me.   I would like to know about the gremlins of the gain mod as Spritzer mentioned.

    I have performed the SRM-727 mod (4 resistors per channel) myself and I can really recommend it. I use it to drive the SR-007_MK2 and the SR-Sigma Pro (which also is difficult to drive) and I like the sound over an SRM-1 Mk2 and a SRM-t1. The latter I like with Sigma normal bias and Lambda...

    Stax SRM-1/Mk2 mod and SRM 727 II mod questions

    Hello to all, I'm fairly new to this forum and untill now I have read a lot of posts to get a bit acquainted. For normal bias phones, I use a SRM-1/Mk2 which I would like to upgrade (actualy a P.P., but I fitted 1 normal bias socket). I have read about swapping out the power transistors...
