Eventide H3000 schematic / service manual request?

Does anyone have a copy of the service manual, or at the very least, schematic for an H3000 Harmonizer by Eventide? Half the power supply went down and after rebuilding it, I still can't seem to find where the short circuit is in the +15v supply...

nice little burn on the board though..hahah
thanks!

sorry, don't have it - but when you eventually find it, make sure to "cc" a copy to our email archive - groupdiy @ gmail.com

That's available for $45 from Eventide: http://www.eventidestore.com/h3serman.html

I'd just ordered one for myself a week ago.

I have  Eventide H3000 with same problem - short circuit in +15v line. Do you know the way how to solve this problem?
I replaced some capacitors (in +15v line), LM7815 and removed some socketed OP-amps (TL072/074), DAC(two PCM53), ATD (Sony CX20018)  - but nothing has changed.

I stumbled upon an h-3000 service manual in PDF form. It's  5 MEG PDF. If anyone wishes to get a copy do let me know.

thanks, i already have a service manual and scheme, but maybe this problem had typical solution or this is due to a frequently-breakdown parts?

well shotgunning anything, just randomly replacing parts, is never really the best way to do things,  I suggest you bust out an o-scope and dmm ans start testing.

A short from a power rail to ground can be tough to chase down with a conventional DVM, since the short appears 'everywhere'.  Most often it is a rail bypass cap, with tantalums and mono ceramics being the worst offenders.

That's when something like a ToneOhm or similar will save the day.  This guy sells something somewhat like a ToneOhm, and also has a DIY decription:

I've had good luck using one of these meters, which are primarily intended for checking the ESR of electrolytics.  But, since it can read down to 0.01 ohms, I can "walk the rail" to find where the short is.
