Can anyone help me biasing a Jadis Defy 7?


I just bought all new Gold Lion KT88 tubes and I am having problems biasing this amp.
I am hoping that someone else with a Defy 7 can help me out a little.
I have the new tubes in and I found the 4 trim pots.
I have been measuring the voltage at the fuses and can not get some of the voltages under 6 volts.

I think I need some help right about now.

Thanks for any assistance!

Mattzack2-
If you bought matched tubes as I suggested, you should be able to keep them together and avoid a lot of the hassle in Schipo's post. The pot sets the bias voltage, and if the tubes are closely matched the voltage readings should be nearly equal. Ultimately they should be close to achieve maximum power, but will work if it isn't. What you are doing is measuring the idle current flowing through a resistor via the voltage drop across that resistor.

It will be worth the effort, that midrange is fabulous.
