    akg k271/k270 elastics/headband

    My fit experiences were very similar to yours, nyumetsu, as soon as I pushed down on the cups everything sounded so much better (especially the bass). I have a large head, and assumed they just weren't designed to fit that large of a head. My modding consisted of using a headband from an old...

    SOHA II Hybrid Amp vs Woo Audio 6 PDPS Tube Amp - Brief impressions with Senn 595's, Grado 225's and Alessandro MS-2's

    Just for reference, the SOHA II was built from a completely stock Glass Jar Audio kit with Sylvania 5963 (12au7 equivalent) tubes. I'm not much of a reviewer...but the most noticeable difference I heard was much more soundstage/instrument separation with the WA6, noticeable even with my...

    I might have good news...after replacing Q8R and Q7L and setting the idle currents I have about another full turn on each pot, does that sound right? Thanks again for your patience and help

    SOHA II Builders Thread

    Update: Well, I finally got some more time to work on it. Things are looking much better. My headphone jack diagnosis from before was incorrect, I was using some really crappy headphones that must have a short somewhere. So when I was moving the headphone jack around it must have fully...

    SOHA II Builders Thread

    Well...I feel pretty dumb, after checking all the resistors several times, I figured out the problem with left channel. I had the headphone plug too far in, since I don't have the front panel on. So I got to listen to it...sounds pretty good so far, however I'm noticing some distortion on...

    I replaced Q1P, and now TB+L and TB+R are both 60V. It also fixed the e12 tripping problem. However the left channel is much lower volume than the right channel. I assume this means I also screwed up a transistor in the amp circuit. And yes, the bias currents have been set.
