Hey synthheads, Does anyone know if you can copy files from an HDD formatted as Optical to W0: or W1 ? The R page "seems" to have a way to do this, but I can't get it to work. The reason I ask is my Opcopy failed at around 9k files of 12k (errors out) and I'm not sure why, as the copylog was unreada...

Hey There, I noticed last night (during a sampling session), that my left channel signal is quite a bit lower than my right. I did all the easy troubleshooting swapped cables/mics &c. but nothing made any difference. Anyone else ever come across this? I swapped the daughter boards around and that di...

Hi Everyone, I know it has been over a year since I started this thread, but I wanted to follow up with you all and close the loop. I was back up and running again by 10/24/13, for a total of ~ 3 weeks of "downtime", and fully operational (with 100k sampling back up) by 11/4/13. SO SORRY for the lon...

Great Leads - Thank You. I got brave last night and removed the Power Supply in question, and things did NOT get any worse, so I think I have successfully troubleshooted the issue.

Does ANYone know where I can get a replacement for an Acme Electric SPW 15-5 and SPW 15-.8? any lea...

Heh ! Well the power comes in and goes to a number of terminal blocks in the front and back of the system. There are at least 4 power supplies in the unit. I think I know which ones are powering the disk drives and the processor, but there are two others. One up close to the top in the front, by the...

Hey There and thanks for the reply. Power supplies for Video Game Arcade machines is one of the first things I learned how to do (so maybe that's good) Can you point me to where that Power Supply is ?

Thanks !!!!!

Hi everyone - I am new to the forum, so if I posted this topic in the wrong place... I apologize. Yesterday My 6400 started acting up, and now has no audio. The +15 and -15 LEDs are no longer lit. It boots normally, and all works, just no sound. I am leaning towards power supply, or one of the inlin...
