Ok so then you have a voltage on the Resistors from 7V, that makes a Current from 16µA, but it should be arount 455µA, this would make around 200V on the Resistor by 440k Resistance.

Can you measure the Current?
The only Thing I could think is, that the Tube is defect. the current is a lot lower than it should be.

sorry,I don't measurement current but I can replace a new tube.

Then try that and measure the voltage again.

Hi Radio martin,it is O.K, voltage is 70VDC around. thanks
can I ask a question a bout this radio;
this radio have a strong bass sound, if I change some capacitor values, can I get a lower bass sound.

When you change the capacitors in the Sound system it can be but normaly it's the opposite way. But if the bass is to much you just have to take them out with the bass Regulator. Mostly the regulator on the left side to the buttons.

I know bass regulator, but on lower bass level again strong bass

Ah so you meand when you put it down it gets lower and then stronger again wenn it should be completely down?

It could help but I don't think so.
But changing the capacitors always give you a better sound then it still is, so thats always a work with success. Maybe the problem will be solved then, just try out.
