Check your tracking number S-Man...the FrankenZERO kit is almost at your house

Hopefully a couple more days and you have it

The diode silkscreen marks are all correct on the Zero's PCB

Yippee! And while I'm at one courier depot shortly, I will stop off at the other one nearby and see if there's a little prezzie for me.

Nearly play time. S-Man

Well I think I'll be ordering from wsz0304 tonight or tomorrow. How long does the shipping usually take for the Zero? I've heard that it's around 10 days.

Yeah its about 7-10 days although since it comes in from a west coast port you might get yours faster. I got mine from WSZ0304 and he kept me informed throughout the process.

Whats involved in swapping out the RCA jacks? I got some free CMC ones from Audio-GD and I was thinking about doing it, then soldering the HDAM ground, then doing the volume pot mod.

True! You can't appreciate a HDAM until you've been listening before and after.

Last I looked, basically pulling out the DAC board which involves unplugging it from the head/pre amp and transformer then unscrewing it from the case.

I've recently purchased this dac, and my unit seems to have a problem with the left channel. The left channel is very muted, but the right one is fine. This problem is present in both the headphone jack and the RCA out. Also when I plug my headphones into the headphone jack, turning the volume causes a muffled scratching sound in the left channel.

What do you guys think I should do? Should I return to the seller and ask for a replacement?

This same thing happened to me when I got mine from Lawrence. It seems to have happened to a few others as well.

What happened was that the DAC opamp was put in backwards, causing it to essentially burn up. Poke around in yours and see if that was done. What I did to verify it was pop one of the headamp opamps into the dac section briefly, just to check... it worked perfectly fine.

I ended up ordering some OPA627's off ebay to expedite the process, because Lawrence wanted me to ship mine back first.

Hope that helps!

Its strange that its affecting your RCA. According to other posts in this thread, it might be a poorly seated Opamp. Try and pull it out and put it back firmly. Make sure those half moon indents are lined up one on top of the other or else youll short out the opamp.

Good on ya, Scorpio, all being well you're going to have a wonderful time, especially if you don't mind the teeniest bit of DIY.

Welcome to Team Zero! S-Man

Hmm, I've reseated the Opamp in the right direction (crescent facing the rear of the unit), but the problem still persists. Any other suggestions as to what the cause could be?

Well, was it in backwards to start? If so it may already be damaged.

Is the Zero as good of a preamp output as a headphone amp? The HDAM and opamp mods wont affect the preamp output in any way right?

its a better dac then a headphone amp. and the HDAM and opamp mods will affect preamp output (granted your speaking of the DAC hdam swap). in a good way though..

btw the zero handles 192000 kHz very well... been experimenting with SRC resampler using foobar2k, and despite what purists say, it sounds very nice. in a word, smoother
