thanks a lot for information.
I try to understand these things better, it's a bit hard to get a complete understanding..
Here comes like always some questions... 1.
Maximum power dissipation is average 5W in g2.
This would in my "mind" mean that with 400volts Plate voltage, the maximum allowable continous current
running into g2 would be 12.5mA. This would give exactly 5W in g2??
So to keep it some lower would be preferable, so it does not exceed this value during signal situation.
Or maybe this is no problem since the signal are supposed to swing same amount negative as posistive?2.
with 250volt at g2, it would then be allowed an maximum continous current of 20mA??
If I understand this correctly with the Currents and power,
This makes your idea of measuring the g2 current a very clever way to check if everything is running fine..
If it does not exceed these maximum power limits, then everything is OK?3.
Voltage Dividers.. Yes this sounds like a good idea.
When getting + voltage from plate then, and divide it with two resistors to ground, and letting the
divided voltage at 250v enter g2, Should there be used any capacitors in this circuit anywhere?
Would it be preferable to have a capacitor bypassing the upper resistor, or lower resistor, or both??
Will this still leave the GU-50 tube in triode connection=?==4.
I don't at all understand when the tube is running like a (Ray)Pentode or when it is a triode.
If we apply a voltage 250volt from B+, then it is Pentode connected.
If we apply the same voltage from Plate, then it is Triode??
Is this because the voltage applied from Plate varies with signal, and therefore vary also g2 voltage
according to Plate voltage?? Is it this that makes it operate more like a Triode?
Thanks for any input, hope it's not to many questions to answer here..
