Am I going to be able to get there with the trimmer/diode and r292 removed?
I still haven't figured out whats going on with Q43. It's obviously been tampered with, his solder looks a little different and he leaves a rosin trace behind. I've read that it needs removed anyway, but I placed my order at mouser or I would have ordered a few to have.
Yes, well pretty close your waveform will be a little more distorted but not bad!
I got a idea for you, Try installing a resistor in series with the diode on the board. Try a 500ohm or something close, It might be enough resistance to drop you negative peaks. It has to be lower than 560 ohms or the current will go through R292 instead of your diode.
