RE: HP-35 Power Supply Waveforms
We double checked and the scheme seems ok,
BTW, I'm right if I consider that Vgg is wrong because Vss is wrong ? I understand well that these two are somehow related ? Reading some of the articles it looks like Vss is a reference Voltage. When Vss is wrong we have read that Cr4 (the diode cathode connected to the cathode of the zener) is a suspect. Is this a good theory or we are totally wrong ? Thanks for help !!!! P.S. : one last question, are the Toroids from classic equal to the toroids from Woodostock ? Looking here https://www.keesvandersanden.nl/calculat...supply.php it seem that L1 has a different value if is from a classic (190H) or from a Woodstock (110H) Edoardo & Alberto |
