Happy Fourth, everyone.

Well, I replaced all the capacitors, including those in the oval can on top of the chassis and the metal box under it. I also replaced the resistors and a couple bad tubes. Problem is I am only getting a hum from the speaker that is not affected by the volume control. I don't get a hum when I touch the center post of the volume control. It does, however, measure close to 10k at full volume - what the schematics says it should be. I need to measure the tube voltages which are listed on the schematics but I don't know how to do it. Where do I attach either the positive or negative probe of my meter? Also, I measured the coils and I think they seem to be okay but could any of you give me the proper way to do it and possibly what the correct ohms should be?

Thanks again for all the help.
