Hello,
I am building the Gyraf Pultec and I am now in the voltage testing step.
It seems that the big capacitors need a lot of time to discharge themselves
(more than 3-4 hours) so I searched and found this thread :
Valve/Tube Safety & Bleeder resistors
I used a 3.2k 2 Watt resistor between the + and - legs of the second
220uf 350V cap (the one with the + connected to the pin 6, A1 of the E88CC tube)
Now, each time I power on the G-Pultec, the main fuze burns
(the fuze that is in the IEC connector, not the 4AT SRP PCB fuze)
This fuze is a 350mA fuze, it does not burn without the bleeder resistor
Maybe I should use a bleeder resistor with a bigger value,
what do you think ?
Regards,
Keefaz
