Is R50 getting warm on yours? If so you have problems. Better to fix it than ignore it and have the amp self destruct.
Well I dumped the badger orginal so it's just from memory.
Many highlights of great designers that's about it and discoverys.
But you could try one if you want.Try this Ips mod a little on your 600W monster if nothing else.
Anatech is more specialist on this honey badger than I am.
So is Terry, ygveous, many others.
Jeff you may need to build one too.

You enjoy designs that don't work without troubleshooting.
Now Jeff I think you like this one.

Tonza75 I measured voltages across my 0r22 with the bias holding a steady 9.8 mv here are the readings 4.7, 5.0, 4.9, 4.6, 5.8, and 4.2mv these are taken with a radio shack meter. Not sure how to check output transistors without causing damage looking into it
Build guide was made follow it. Go to a friend with oscilloscope, signal generator, you'll figure it out.

Use ltspice too after all it's a proven design you'll master it pretty quick. I'm not sure if the designer was a licensed ltspice user ask variac. As you propablly know without a certified license, simulation is likely to go wrong.
But I thrust you are a handy guy with time. Put pcb traces + power supply in simulation to get better results real results.
EITHER WAY enjoy the amp.
ROCK 5.8mV / 26.36mA on the one transistor, inspect that one I suggest.
Might be one of the reason the bias jumps suddenly.
Pot trimmer is useful, don't use a screwdriver that grounds you at same time.
Try to turn pot slightly, is the difference bigger in %
on the 5.8mV vs the rest output transistors.
Matching transistors, many don't on this topic, issues on that elsewhere.
1 more cup of coffee, grumpy goes away!
Have a good day, I might get grumpy in the evening 🙂

Another thing which isn't in the build guide is bench test results for the Honey Badger. I assume the designer published these somewhere. Does anyone have a link?
I actually bought some HB boards a few weeks ago and was planning on getting started on this build. Just last night I just got my hands on cheap and broken Sony TA-N80ES.
Should I fix and do a complete recap on the Sony or continue with the HB build? Is the HB and better performing amplifier? I supposed I can do both, fix the Sony and build the HB but one of those projects would have to be put on the back-burner for a while. For now I'd like to work on the project that will give me the best performance.
Thanks guys.

The HoneyBadger is a very good amp. I have no experience with that Sony, but I would be surprised if it would come close to a well built HoneyBadger. I'd suggest to give birth to the HoneyBadger first.
Maximum Voltage?
Hello, I have decided to build a couple honey badgers for home and work.
I have a couple donor heatsinks/xfrmrs from some 1600W Bass amplifier heads. The heatsinks are HUGE.
The transformers have a 60V HT winding which should yield 80V+ rails.
How do I determine the maximum possible voltage for this circuit, or any SS circuit? I deal with tube amps every day where there is much less ambiguity on voltage.
Is it just a matter of proper heatsinking, correct bias, and using high voltage transistors? Is there anything I should change right of the bat?
I am not absolutely set on using those transformers, but I sure would like to, and for my situation more power is certainly not a problem. 🙂
Thanks for your time

the output trannie Vceo, should be greater than the sum of the rails, so that +-80 volts, you need the output devices and drivers to have >>160 volts spec..
same as the VAS trannie and the big CCS.....

that high railvoltage is not a good match with only 3 output pairs. it will be fine if you ONLY use 16ohm or higher speakers.
