Now that we solved with a lot of help the question of muting, time to move on to the next question. First, remember I'm rather dumb about electronics but have figured out the usual stuff. I will post a link to the schematic of the 38-116. The one I have works quite nicely. The mag tuning does not work. Tubes test "fair" at least not shorted or dead. Transformer tests good for the mag tuner circuit. Problem is going through the alignment of it, neither the 53B or 53A alignment caps do anything! They will not change the 100KC signal although it runs through to the speaker nicely. Just no adjustment.
By the way, the cap in that dang RF unit I can't reach is the .05 listed as #7 on the schematic, in the antenna area. I suspect it doesn't see much voltage. I may leave it alone unless Ron holds his class on taking out the RF deck.

Can anyone out there suggest a trouble shooting sequence? I have a scope, generator, VOM and digital DVM. I just do not know how it is suppose to work. An explanation of that would help.
