HP-35 Power Supply Waveforms

Dear Alberto,

I think you are right! Sorry I confused you. I only read that part of the guide but not the part that begins after figure 6 but is crucial.
If you followed the guide from scratch you removed all 3 voltages from the rest of the calculator circuitry (CR1, CR2 and CR4/CR5).
Installing the board at this part of the guide only is for getting connection to Vbsw I guess (what could be done also otherwise).
