[R-390] Smoke got out

[dog]

All the filament wires (white/black stripe) that go to V203, 204, 205, 
206, 207, the tubes in the rear of the RF section, show evidence of over 
heating. V202 and 201 do not show that. But I cannot find any shorts, 
anywhere. I haven't measured the bypass caps yet but they would show up 
right on the filament line if they were shorted. Looks like I need to 
replace all that filament wiring from the jack to the tubes, some are 
burned enough to show bare wire. I'll have to look at that harness with 
P108 and see what it looks like going back. That wire is showing bare 
wire too. Something happened.
