I know this is rehashing an old thread, but some observation:
The 45 side of things doesn’t exactly work correctly.
1. The feedback for the script/block option should be coming from the common side of 45/90 switch so it can be taken in and out of the loop, as such the way it is designed.
2. On a phase 45 the feedback comes back in on the investing input of stage 1, vs stage 2 on the 90. Would need to change to a dpdt switch to fix this (and I may do so when I get some long leg pots in to leave clearance for a handwired switch vs PCB mounted switch… but it would be proof of concept only, since I do not see myself using anything other than the phase 90 mode)
As such, script mode for the 45 works, but block will never work correctly as it is. The irony is, there never was a script phase 45, only block.
Again, I mean no disrespect , and if I’m missing something obvious, please let me know.
EDIT: I just tried a Phase 95 side by side with this build, and other than a slightly weaker phase (trim adjustment needed), the same behavior on the phase 45 setting is happening there. Confirming that the error is not on the P-PCB end, but rather a design flaw (or should I say, “cost driven design compromise”) on Dunlop!
