[QUOTE="GuitarGuyLP, post: 107590, member: 1848"] OK I just heard back from Randall, and they did some searching. The change is to R35 from 1.8K to 3.3K, or 3.6K I will put the original R36 back in, and change that one out tonight. I will report back once I have made that change so that I can pass on the proper information, but looking at the schematic increasing R35 will have the same effect as lowering R36. I just hope that R35 is a bit easier to change out without removing the PCB. R36 is a bit of a challenge especially with ROHS solder. [/QUOTE]
