Maulrajas I will report back and get in touch directly if there is a need. Will the DY tester be good enough to check all the parts for the T2? I would not recommend doing anything unless the crackle comes back. Do not stack the metal cases while testing. Same on two headphones and same after switching both sets of tubes from left to right in sequence.

I adjusted the batteries to what I believed to be the center of the sweet spot. Maybe switching them did something. Not something you want to mess with though. Has anyone sold theirs, I wonder? If you do open it up, make sure that all power is removed and that any high voltage capacitors are drained down first. Is this about right? Posted Dwtasheet 27, edited. Posted March 20, I believe it does self-bias the tubes, am not really sure — I have not built my T2 yet.

I moved my DIY T2 from Mayberry back to SF without incident but was listening tonight and there is a persistent static crackle in the left channel.

Ah, well, they datasheeet that electroshock is an effective treatment for depression, so maybe some benefit came of it.

If the DY is only good for weeding out the obvious fakes, what would you guys suggest for a good test box. In any case, would you be willng to share your source once you have secured your allotment? Basically the datasheett need to be adjusted to V and then the servo can kick in and null the output.

Of course, I sat down the headphones for awhile with everything on and now I do not hear the sound. Posted March 27, Low voltage is more of a problem though as there are so many similar parts out there. I have no issue buying one if it will do the job.

To these untrained eyes the data sheet seems to suggest only that 30 is a min. As an aside, does anyone know a reputable source for the 2sc and 2skgr — have been searching for some time 2sc no success. Sign In Sign Up. Posted March 20, edited. Glad that the crackle is out for now. Everything indicates that there should be 36 in the package. Needless to say I was not happy. Even though they are matched there are still variances.

Would one of the test sets like mentioned a couple of posts prior work for this? I hope there is a positive outcome. Just seeing this now.
