I'm with Mike the plate volt is WAY HIGH at 400 something volts. The 6F6 should load the hv line some but it seem the that isn't happening... Acts like the tube heater (the part that lights up) is burned out.  Max plate voltage for the 6K7 isn't anywhere near 430v more like 300v. Make sure pin 8 of the 6F6 is grounded and you should see some -voltage on pin 5 of the 6F6 too. About -10 to -15v.
