Quote: Yes, I've definitely reset it via both the reset button on the top and the reset in the settings menu.  I've tried pretty much everything possible short of opening it up and poking around with my meter.  I even tried using an L7 dock for the USB in and line out and neither of those...

Quote:   It has almost a full battery.  I do keep the USB charging off until it's down to 1 bar, then fully charge it, and then turn charging back off to keep the battery well conditioned.  I've seriously babied this thing, which makes it even more frustrating that it's no longer working.

My E7 stopped working after about a month.  It turns on and is recognized by my PC, but I'm just not getting any sound out of it.  I've also tried to connect to my iPod line out and the "Aux In" is displayed on the E7, so it recognizes the iPod, but still no sound.  It's like the amp portion of...

Quote: I actually did do a search on Mouser, but it was on the part #, not the description, and that's what got me in trouble.  When you search Mouser for 71-RN55D-F-121 the first 2 of 3 results are 120K ohm   Bottom line is I should have paid closer attention when ordering.  Thanks for...

Ok, I'm a dumba$$....  On the BOM, the Mouser link for RR1 didn't resolve so I added the part on my own, and inadvertently added a 120K ohm instead of a 120 ohm.  Thankfully I stumbled across a LM317 calculator which helped me realize my problem.  I can't believe I did that, but I guess I'm glad...

Ok, I've done some more troubleshooting.  The issue seems to be with RR3 or something related to RR3.  If I remove RR3 from the circuit voltage slowly builds to 30V+ at v+.  As soon as I put RR3 back in place voltage drops to next to nothing.  It doesn't seem to matter where RR3 is set, just...

Quote: I'm pretty sure I've got the regulator aligned correctly.  It really seems like the regulator isn't working correctly.  I hooked my meter leads directly to the ADJ pin and to GND and can dial in a resistance range of 2.0-3.1K ohms.  Does that range sound about right? If it's not...

Quote: I'm building the Mosfet MAX V1.2.  I've checked CR4 as well as all 6 diodes and they all are aligned correctly.  RR3 may be bad but it seems like it's working.  I hooked my meter up to it and am getting a range of 1.0 ohm - .99K ohm.  Interestingly, if I bridge the output and adj...

Hi, new to this thread (and amp building), and and am hoping to get some help with my Max build.  I finally got it all put together but when I power it up I only get 1.6V to V+.  I do have 36V going to the input on the vreg.  Adjusting RR3 doesn't seem to have much affect on the output voltage...
