I believe 30-ish mA is about upper limit for a 130w tube-

set your machine to run a vector pass at full power... set your speed at 100 and your power at 65%.

Watch the mA meter- if it's running above 30mA, then lower the power in 5% increments till it's no more than 30mA...

Likewise, if it's below 30mA, raise the power until you reach 30...

Whatever the entered power percentage is, THAT is your "100%" power setting.

Example, my 80w Triumph hits a solid 26mA at 70% power, so 70% entered = the machine's 100%, 35% = 50%, etc.

If your outputs are similar, then the 30% power you set would be around 60 watts actual output, which may be a bit high?
Actual output is good to know so you don't overdrive the tube - you CAN go beyond, but tube life will be shortened...

Try running the same thing at 15% power and see what happens..

Hello,


I have performed the tests and with 78% power 30 mA.


Thanks for this recommendation, it's helpful.


But the problem continues, tonight I have an engineer from the Chinese factory and I have to do tests to find a problem.


When you have it solved, I will notify you.
If someone else has any ideas, it would be very helpful.
