RE: HP-35 Power Supply Waveforms
We did it !
We created a micro circuit, a resistor, the diode and a 9V generator and measured the real value. We discovered that the zener with which Vss and Vgg where very high had a voltage of a little more of 9V With the replacement, which has a voltage of 6V we have Vss and Vgg much more close to the correct values (see pictures in precedent post) Should we try something lower to get the exact Vcc, Vss and Vgg values ? Thanks for help, this is getting interesting Edoardo & Alberto |
