First of all, try another tube for V2. It appears one side is not drawing current. Don't assume your tubes are ok even if they test good on a tester.
Check R9.
Second R48, should be a jumper if it isn't there.
Third, you seem to be grasping at stuff. It may be time to get some professional help. That repair should be under $100.00.

Hi
This is not a tube problem, I have test them and put good, but cheaper, tube when I do test. I will check for R9.

Check also the grid of that tube (pin 2 or 7). It should be zero volts dc.
