| KungFuJosh:
R5 at 5.1k is definitely better. Now I should go to bed 2 hours ago. 😬 |
| coromonadalix:
the best results so far |
| TERRA Operative:
You almost need a breakout board like a mini 'mixing desk' of trimpots to tweak and dial them in to get it perfect, then substitute with the closest fixed values. :-DD |

R1 was okay, R6 did nothing, and I think R5 hated not being a fixed value for some reason. 🤷 I definitely think it's easily usable now, but I might try 5.6k in R5 as R5 seems to directly affect those corners. My only concern is that it might cause some more ghosting. I also think it looks better in person than in the photos. In reply #110 above, there's a high resolution attachment you should be able to view the chip markings on (the one with the -min suffix). Thanks, Josh |
