Just saw your remarks about distortion on your 90. I noticed some mild distortion on my radio also. I attributed it to the 45 output tubes which have tested very weak, and since they are quite expensive I have not replaced them. I also have not done an alignment yet nor have I measured the plate voltages on the output tubes,or any other voltages for that matter. I want to install a bucking transformer in the cabinet as my line voltage runs about 125V. I have put the chassis aside for now until I get the cabinet refinished. Too cold now to tackle that-is -13F as I write this. I guess I was so relieved to get the radio working considering all the unknowns with the sch. ect. that the slight distortion I heard didn't alarm me very much.
