Help! I got a stock UA-5, had a ts.com buddy mod it, and it worked great, for two shows and occasional use as a DAC for my headphone rig.
Suddenly, last night, while listening on headphones (CD player optical out -> optical in on UA-5 -> UA-5 RCA out to headphone amp), the music degenerated into a staticky mess. I tried every combo of cables/inputs/outputs: optical in, XLR in, RCA in, optical out, RCA out, headphone jack, out to JB3, out to headphone amp, out to headhpones, even the L&R 1/4" mono outs. Every combo produced just nasty static!!!
I turned on the JB3 to record a sample of the static (this happens to be CD walkman -> RCA into UA-5, optical out to JB3):

I haven't dropped it, ADV mode is off, and wiggling any cords or shaking the unit itself does not affect the noise at all. I checked the mod and it's all clean: the R8 resistor contacts aren't bridging and the wire jumper is bomber. Batt or wall-wart, the same.
Today I turned it on again and it worked fine for about 45 seconds, then degenerated into total static over the course of about 10 seconds. Power off, power on, and immediately it's static.
Does anyone have any insight as to what this might be??!? Is there anyone that works on DIY-digimod UA-5's? Thanks!
