What is the relationship between the 120K resistors and the filament voltage? That's new to me...... Those flybacks are either dead or alive. good luck Jorge At 12:31 p.m. 24/02/2004 -0800, you wrote: >Has anybody ever had a filament problem were the flyback was the problem? >I've done everything with the Daughter board and the 120K ohm resistors.
