My wife has tinnitus, and she uses a simple relaxing technique that was posted here at HeadFi, some time ago. It works something like this: Put on your headphones, and adjust the volume so that it is several notches lower than your usual listening volume. Lay back and relax. Within a few...

With all this troubleshooting going on, I thought it would be a good idea to share some of what I know about the Zero, from a slightly different stand point. Many of you don't know this, but the Zero has been sold to members of HeadFi, dating clear back to August of last year. That is a year and...

Just an update on where I'm at with my FrankenZero. My compliments go out to PP, who dreamed this whole mod up in the first place, and made it a reality! PP, Sir, you ARE the "Steely Eyed Missile Man" of DIY. Good on ya! I've got about 1200 hours on my FrankenZero now, and he's stable and...

For you guys who have done your FrankenZeros already: PP and I both noticed that as the PIO caps mature, the soundstage can change drastically by going from narrow to super wide and back, and the upper highs and lower lows, can come and go as well. Since we had the exact same thing happen...

I've found these on ebay, and they are the real deal!! BIN is a decent price, so if anyone is looking for matched Sylvania 5654's with round getters and black plates, this set seems like a good deal, but it ends in 5 hours or so: Sylvania JHS 5654 6AK5 EF95 Matched Pair Little Dot Amp - eBay...
