T-4XC recently refurbed by pro. Was working like new. Suddenly cannot load on any band over about 10 watts out. Plate current limits out at 100 mils+/-. thought it was PS, changed to different AC-4, same results. Swapped finals and driver tubes. Same result. Looking for pointers on where to start my search. Think a component in the PA has failed. Have not started diagnosis. Will be doing resistance and voltage checks per manual. Any and All ideas accepted!
