Can anybody with a two tube 2500 Commander ( those with grid trip protection) tell me at what grid current their amp trips out at? ?I have an older model in for work and it doesn¡¯t have a grid trip. ?I put a trip circuit in it and wanting to adjust the trip point to factory specs. ?Schematic had a notation 65ma max., but that might be for a single tube. ?If anyone can let me know what their¡¯ sis set to I¡¯d like some input. ?Thanks, Lou
