The 3/10 amp fuse is for the horz current so Don't worry about that yet. I dug out my 5 and did a double check on the 6cb5 cap voltage and I get 385vdc on that cap. Also my ac line is set to 114 ac so it would be lower than what you would get at 117vac. I think you found your problem. Just to make sure, Check pins 4-5 on the 6cb5 and make sure you have drive voltage. It should be around -30 vdc. Also check pin 7 on the 6cg7 {horz osc}. Should be around - 70vdc. Lets make sure the b+ is getting into the horz osc. Now please go to the yoke plug and see what you get on pins 7 and 3 and Make sure the yoke is connected. The voltage should be at b+ or a bit lower.
