content: I've got an old Adret CV102 Voltage Source.It works so far, but needs some cleaning and calibration.Unfortunately I didn't found any documentation (User Manual, Service Manual,..) on the net.I would really appreciate, if someone could provide such a documentation or any additional information regarding this Voltage Source.Thanks

content: Hello,I'll ask here again, maybe there is a new version.The manual for the CV102 that you now find in EEVblog ends with chapter 6.As you can see, the circuit diagram starts with chapter 7. Is anyone inpossession of this circuit diagram and can send it to me by e-mail?My device has a fault and I want to try to repair it.The voltage at the output is always 3.19V in the 10V range and 31.9V in the100V range and cannot be changed.Who can help me?Best regards, T.K.(Translated withwww.DeepL.com/Translator, I speak German)

content: Hello to all, especially to Mr. Jacques,the fault has been found, a defective tantalum capacitor 47µF on module 0131. now all capacitors have been replaced and the device is working again, but there is still a problem. the manual describes the adjustment. but the adjustment to zero with R22 does not work. i cannot achieve a positive value, the setting ends at -0.074 mV and never becomes positive. i have also measured that thesystem clock operates at 1.624 MHz. how exactly does this value have to be correct? does the clock have to be set exactly again? the manual gives no indication. what else i have done...all TTL-Ics have been given a 47nF capacitor on the voltage pins for better performance.Thanks and best regards, T.K.(Translated withwww.DeepL.com/Translator, I speak German)
