MasMusica | Re: Power Ground Thank you for your reply. I understood or at least I thought I understood that a power transformer with a center tap has the potential to short out the heater winding, so as a safety precaution it is suggested to put a 47 to 100 ohm resistor at the end of the center tap lead, so that if it shorted out, the resistor would act as a fuse? I just want to be sure that I don't fry my power transformer and have to buy a new one. I'm fairly new at all of this and I've seen post where some guys opt not to use the center tap to ground and will create an artificial center tap using 2 100 ohm resistors, I guess just looking at it from a practical sense if a transformer has the center tap on it why do some guys opt not to use it. Thank you for your patience, i look forward to your reply. |
