I finished building my Minimax, and is just trying to bias all the stuff at the moment. The tube bias is giving me some problem. diyforums says that the prefered range for the tube voltage from the 2 test points are each supposed to be half the powersupply (~12-14V)but mine is at 21V with my...

I just finished populating a SOHA kit that I got from glass jar audio, I'm doing some test with the voltages, all the points checks out except for the 2 marked as +40v I know i have to adjust the pots to get it to 40v, but I cant seem to get the voltage pass 30V, then turning hte pot who have...

I have recently acquired a sextett in pretty bad condition, I have ordered parts to clean and fix it up. But now here's the 2 dilemma: -Should I use the spare AKG stock cable from another one of my vintage AKG that I had re-cabled to keep the unit "stock" (or OEM) or re-cable it (but that...

I emailed grado labs to see if I can get a replacement headband (the RS-2 ones) for a Grado HF-1 that I am recieving, and this is the reply I get: Quote: Sorry, we do not sell parts separately. Grado Labs what's going on? I know quite a few people here at head-fi has gotten...

I got a friend who wants a pair of decent gaming headphone for <$100 he loved my k518dj when he tried it, but is still hoping to find something even better.. if possible. My guess from what he listens to, he's prob a basshead. oh.. and his only criteria other than good sq was that the...

I saw Xin's super-micro was able to use just 1 AAA battery to power the opamps, and also claims its boosted to 5.5v. I was wondering how this was done and is it possible to adapt this design to my DIY cmoy. I would love to have a tiny Cmoy that could fit on the back of a ipod nano.

I built a battery powered PIMETA and noticed that after I put in the JFETs for class A bias, it seems to be draining the battery much faster than before the bias. anyone knows why?

i got a low impedance headphone: k518dj's, would adding a 150ohm-220ohm vishay precision resistor make it sound better? or more importantly help make it sound better on a amp?

are these real? ebay: AKG k141/2

I got these off ebay, and loving the sound so far. I've already replaced the jack with a gold-plated 3.5mm neutrik plug... didn't make much difference on the SQ though. Some folks at the Head-wize forum has given me the AKG service parts # to fix up these headphones Just want to...

I loved my G5.5 U2 edition ipod, but the battery is starting to die.. and apple makes you pay sooo much for a battery replacement... so i bought a ipod classic off ebay. THe silver back on the black ipod classic.... with all thte minimalists at apple's design department, i cant believe they...
