When taking ground referenced measurements leave the (-) black lead on ground and the (+) red lead on the measurement point, that way I can tell if it's posistive or negative.
Let's take it back one step...
On the EF3 board measure TP105 (+48V) and TP106 (-48V) referenced to ground.

You are in good hands, listen and follow, Jer will get you there. 😉

Scott, this could be really difficult to diagnose. What would make it easier for you and us trying to help you is.
1. Remove the amplifier modules from your chassis.
2. Separate the IPS and the output stage board.
3. Take some clear high resolution photos.
4. Use the build guide and check over your boards.
5. Start to test each board individually as shown in the build guide stating with the IPS board.
6. Work through one step at a time and report back with the step were things aren't correct.
This will make the whole process easier.
Good luck
Stuart

0.000042 % THD + N at 1 kHz
Those are impressive measurements. Thank you.

Heyenc, this is the final step of the design process, what we designed for and it is confirmation, finally, that we, collectively, did it.
More importantly this is what the current design, BOM and build guide can deliver when any DIYer builds it.
(but yes, I am sure it will end up in the Build thread too)
Hello everybody. Looking at the Osstriper PCB, why are the resistor and the suspended capacitor referenced in the GND of the speaker and not in the star G2? Thank you for your patience and care.
Please provide a clearer question. Maybe a photo, sketch or post number.
So we can try and help you.
RLft, diodes D1 e D2 e CLft, could it not be referenced in the G2 star?

Hi CLPK, we did this to separate the Signal Ground from the many and higher currents flowing in the Power Ground. The placement of those traces also avoids nearby noise sources. There are other areas where separate tracks are used, in the feedback path for example, in order to achieve the extremely low noise and distortion floor of the overall design.
I understand, is that why the negative feedback is also in parallel with the GND speaker?
Hey, it's Dbl.aa
I think I want to build Honey BADGER BUT WHAT ARE THE POWER OUTPUTS(RMS)
and can it be built like mono blocks?
Thanks for help.
I have very little knowledge other than researching the last cpl years as far as building circuits . Plus I suck on computers and NEW TO USING ANY FORUMS.
So excuse me if I'm a little ruff around the edges.
I REALLY WANT MY AMP (BUILD) DIY KIT /PARTS LIST TO ORDER . ANY TIPS. WELL APPRECIATED GUYS🤠
