Gotcha! I'm not super familiar with this set of boards. I do like those snubber boards that sit on top of the rectifiers, though!
^ I'm a big fan of Randy's PSU layouts. I also love the snubber / rectifier boards. If you haven't tried them... I gotta admit ... my absolute favorite little gem is the soft-start / safety cap boards.
@ItsAllInMyHead answered the question and I'm just adding a photo from Randy's build guide. Sorry I missed that in the massive photo dump.
Not cheap but looks like a great way to implement two-way active crossovers. https://danvillesignal.com/dspnexus-dsp-audio-processor
Up next in my build queue: The F4!
Stay tuned! hehehe
Thank you again to 6L6, who's been a tremendous help to my incessant build fever!

DrDyna,
Good to see the progress on your build.
Another shout-out to 6L6 - Jim, thank you for putting together the detailed build guides, and being an active source of guidance and encouragement to DIYers on the forums!

Got a small issue while trying to finish an F4.
testing one channel at a time. The first one I tried to bias starts out at 210mv but continues to climb up over 230mv and doesn’t stop. I will note that I added a 10k resistor in parallel to R9 during the build.
I checked all solder joints and they look good.
Psu Voltage is stable at +-22.40 Volts.
Any help is appreciated

I would reheat each one from the top where we can see, heat for a couple seconds, and then add solder.
I just tried the opposite channel and it didn’t fire up as high as 210mv. It started up at 160mv but it did the same thing and kept climbing upwards.
I wonder if I have the wrong diodes in D2. I bought them at a local electronics store but could have grabbed ones not in the right location.
