Signal injection:
To test IC op amps or preamp tubes stages with a sinewave generator and a LAMP or LED not a oscilloscope
I place the sinewave generator on the input of a IC op amp , than i place a LED from ground to the output of the IC op amp, it burnt out my LED why?
what can i do to make this work? my LED or LAMP can't take the voltage GAIN of the output voltage of the IC op amps, what can i do to protect the LAMP or LED so i can probe any IC op amps output with alot of current or voltage gain?
I place a sinewave generator on the input of a tube preamp , than i place a LAMP from ground to the output of the preamp tube, it burnt out my LAMP why? the glass of the LAMP bursts why? what can i do from making the LAMP's glass bursting from the high voltage?
