Re: MAC RACK KIT with Green MAC & DINGO PCBs Build Thread

Or i could take another LED and try it outside the meter? By the way - is there an easy way to open the meter and change the LED?
Thanks a lot for your help, Joe!

Re: MAC RACK KIT with Green MAC & DINGO PCBs Build Thread

Hello Joe, the meter light of my MAC has gone dead and i wondered if there's voltage on or if it's the light in the meter. Took the multimeter to it and got +30 volts ... :? So there's additional wondering if something on the board crapped out. 30 volts seem a bit high and maybe that blew out the li...

Re: MAC RACK KIT with Green MAC & DINGO PCBs Build Thread

Sometimes I like the action of the MAC compressor better than me continously adapting the gain of the preamp to softer and louder parts. :D

Re: INX5 BUILD THREAD

This thread when finished became the BA500 and LA500 threads. Both units share the same bracket so best to look at there build threads to see if that bracket would work for you. But it needs a meter to hold together properly. I guess I could make it work :) Feeding a mic into a series resistor feed...

Re: INX5 BUILD THREAD

Sooo.. apart from the input impedance... the only question seems to be if you got two of those steel brackets in stock, Joe.

Re: INX5 BUILD THREAD

Under Construction INX5 + JLM GO between PLUS kit makes a 51X or 500 series Mic preamplifier (edit: read through the Dingo thread and here's my conclusions) My MK-U47 condenser mic (ioaudio, groupdiy) has - like so many condenser mics and some moving coil mics close to a loud source - a really high...

Re: MAC Build Thread

Here's the Koala I mentioned three posts earlier :-) knobs are available for guitar pots, but they look nice here, too.

mixup on the overview of the general MAC PCB?

Looking on the MAC's in the case (page one of the thread), the switches are (top to bottom) ratio, VU, sidechain lowcut on the frontpanel - but on the overview of the general MAC PCB wiring if the blue trimpots/wiring for the pots are on TOP, the switches are (top to bottom) the other way round? So ...

Re: DINGO PCB and kit BUILD THREAD

Another successful JLM build! :D I did the Pultec clone from the NRG forum with a Dingo and two 99v http://www.nrgrecording.de/nrg/viewtopic.php?t=91&postdays=0&postorder=asc&start=0 and even if there's a rat's nest of 36 wires from the board to the pots and switches (thank god for multi...

Re: DINGO PCB and kit BUILD THREAD

My slow build... (better slow than faulty) I hooked the Dingo (without the 99vs in their place) up to my +/-24v AC/DC and measured at the opamp socket pins with my DMM. Plus and minus 24 volts are +24.4 /- 24.0, 0 volts is 0 volts, fine. (just made a note to revisit the trimmer on the AC/DC to get t...

Re: DINGO PCB and kit BUILD THREAD

I have been at my Dingo over the holidays and came up with a few questions. C 1+2 no strip on the side to mark "minus" - but legs different, the shorter should be "minus", right? C 5+7 / C 12+13 = are 16 volts, but 25 volts rating on the schematic.. (with my +/-24 v PSU) I guess ...

Re: New JLM 16v 99V

I'm glad that I asked! Thank you, Joe! I'll try and check the circuit of my Eisen pre and the action compressor to see if they got output caps. :D
Update: EisenAudio DIY500 MK1 preamp checked, C9, 470µF/16 bipolar. That should work.
