Hybrid+ From Digilander doesn`t work
Perhaps anyone can help me:
I bought two hybrid+ from generoso cozza. :mad:
I build the supply for the heating, and the time delay and the ps for the PowerMosfets myself and they work.
When i switch on the hybrid+, the mosfets and the resistors in front are burning.
I dont know how to adjust, and find out where the problem lies.
The only thing Mr. Generoso tells to me is: "it must work".
I should say, that i have build several mos fet amps without problems.
Can anyone help me ?
First I should say that I have not had any experience with this kit! I have read acouple of articles about it though.
I would start by checking the voltages in the valve section and adjusting the bias pot P1. If it is burning resistors when you turn it on, I would remove the mosfets, or at lease the grid stopper resistors.
You may not be particulary interested in this at the moment, but
http://www.tubecad.com has done a review on the circuit and proposed some enhancements. If nothing else it shows the voltages in the valve section more clearly (in particular try http://www.tubecad.com/march2001/page21.html).
