Last week I have received the six8zero machine's  schematic and Service manual. Planned upgrade some of the lytics to Rubycon Z low ESR.

Sweet! Can you post the service manual too? Looks like the three documents are only schematics and do not include assembly instructions.

I would love to know how this turns out; it's an interesting idea to say the least. :)

I'd like to see the service manual too.

Maybe you can post it on a free file share site and post the link here?
Or email it to someone to do that for you?

I have a playback question for my DR-680 - I've never tried to playback the files directly on the machine but rather have always just copied the SD card over to my laptop and messed around with things from there.  Today I tried to play the files directly on the machine - I selected Browse from the menu and when I highlight a certain take and select info, it says "Irregular File" and when I try to play it it says "File Not Found in Take".  The files copied over to my HD and play fine there - anyone know what's up?

Sorry, haven't checked this thread in a while.  When I move files from the machine to my computer I often "cut & paste" (cut) instead of "drag & drop" (copy).  When I do this, the file name still shows up in the 680's menu.  When you do Browse>Info it then shows "file not found in take" as you described above.  Essentially, I think if the header information is present, it will look for and play the file correctly (assuming it's the same file that the 680 recorded).  I am not removing the SD card from the machine when I do the "cut & paste" as described.  The only way to get rid of the file names is to format the card.  The card still says the correct amount of free space is present, but for whatever reason keeps the file names (header information) until formatted.

I assume if you record with the 680 and the file is still on the machine, it will play back properly.  I have played back the files in the car (once/twice) on the way home to check them out - simply using the headphone out to AUX in on the car stereo.  I have also listened through headphones at home directly on the 680 without issue.

Cheers,

Matt

Question about internal batteries:  I notice that the Power button is really a Standby button. is there a way to actually power down the unit, so as to not trickle the batteries down?  After recharging 8 NiMH batteries I did manage to get the unit to power up vial the 8 AA internal batteries.

Thanx
-- Ian

I will say that I've noticed something: I use DVD batteries, with AA rechargeables in the deck at all times for backup.  If I keep the DVD batt plugged in to the deck even when the unit is off, it does drain the battery.  I get 4+ hours with this particular battery, and left it plugged in twice (deck is "powered off", but cable from batt > deck is still attached).  Both times the battery was empty when I went to use it again (fortunately I always have a 2nd battery).  I can't comment on the drain on the AA's, as the unit will use what it considers AC power (anything plugged in to the unit) before it uses the batteries.  I did have some life left one of the two times mentioned above.

Cheers,

Matt

I have done this with several digital audio devices it opens the sound. You you have to carfully  unsolder the things,  not to damage the copper on the printed circuit. Some of them have multiple layers the I cut off the old caps and solder it to the old wire on the board. I strip off the plastics from the caps.  Dont want to fight/discuss this in detail it sounds better. Swiss genius Serge Schmidlin recommend it.
