what is LMC
Don't know if the only difference between the 149 and the 249 is the change from a Gain Pot to a Gain switch.I will see if I can get some pics.Better would be to see the schematics
I could do a quick layout for the G series pre. Link to schematic?
Thanks for the upload! The mic gain switch is removed from this schematic. I assume it's attached to MOL1 MOL2 and MOL3. Do you have that drawing as well?
