agreed with most above i am. id like to add alittle info to hopefully take the mystery out of waveform ringing. A digital signal entering a chip (like a DAC) will only cause audible "jitter" if the following conditions are met:the DAC's power supply isnt "weak" under full output (ie. well...

I've been meaning to post about the capacitor controversy but have been designing a valveless engine in CAD. Anyways, I took a break and maybe i can clear some confusion from the thread. As you may know, capacitors used for coupling have a unique frequency response depending on the impedances...

What qualities would your dream amp have?

Perhaps you had the tube in question ARC over, in this case, aside from discharging the caps (could contain a few joules worth of electricity?! - enough to toss you like a rag doll!!) and replacing the resistor which is a 10 ohm 5% and looks to be a 1W. Definitely have the tubes checked before...

Just tried to reboot again... nothing. Need parts ?(less a logic board of course, lol). Had another thought on the "fat" nano, with 4GB, hell even 8GB capacity at lossless bit rates, (which i don't think it supports it anyway), you wouldn't exactly have a whole lotta room for lossless files...

Allow me to elab. Following the picture in the first post for the short & wide Nano where you thought the LOUT/ROUT would be, i attached very small Magnet wire (radioshack), to the DAC side of the caps, ran them to the dock connector, which i then ended up solider bridging about five of the...
