Re: DINGO PCB and kit Now Available
I would like to build a Pultec'ish EQ with the DINGO, using my own filter circuit and have some questions: For debalancing / input impedance matching I would like to use the Hybrid or 99V opamp. Does the first opamp contribute noticably to the sound as it has gain = 1? For gain makeup, is it possibl...

Re: Questions on OP:s for Baby Animal
ok, thanks for the info, I was wondering why some would open (like the dual BA pdf) and others would not. But Acrobat Reader opens them all. It is a shame that people are misusing your schematics, btw. your PCB layouts are a work of art, keep up the great work!!

Re: quick Q - FET DI hookup?
thanks, that clears it up! The preamp has a "mute output" switch, so I'll probably leave it as is and pass the phantom power through the DI.

Re: quick Q - FET DI hookup?
another short question - I am hooking this up in front of a preamp, will the FET DI have a problem with phantom power appearing at its output? And will it pass the 48V through to a mic connected to the input posts?
thanks, Marten
thanks, Marten

again :oops: my bad, nothing was broken, I just had the trimpots turned fully clockwise, which gives maximum voltage - from there you have to give it a couple of turns counterclockwise before the regulator starts bringing the voltage down. Now got +/- 15V and 48V and everything is perfect. http://ho...

JLM AC/DC troubleshooting
ok, I need a little help troubleshooting my busted AC/DC powersupply. By stupid mistake I messed up the power transformer wiring and some caps went poof :oops: Now that the caps are replaced the 48V section is fully functional, but the voltages at the V+ and V- just sit there at unregulated DC volta...
