I'm in the process of restoring a console model 41-280. I have a replaced the caps, the power cord, and verified the tubes and speaker are ok. I felt my next step should be to check tube voltage and this is the results: 41 output tubes read 160 and schematic says 175. Didn't check the 7c6 audio as the schematic dosen't give any value on voltage. Both 7b7 tubes read 158 versus 180 on the schematic. Finally the xxl tubes read 66 and 31 versus 95 and 40 on the schematic. My questions are are these readings acceptable and am I going about this in the right manner. This is my first attempt in restoring a vintage radio as you can probably tell. Any comments will be appreciated. Bill
