Horloge à VFD false voltage in IC1

Postby mlouison2 » Fri Sep 28, 2018 8:52 am

Hi,
in my assembly, the voltage between pins 2 and 3 of IC1 (PTH08080W) is about 0.300 V while it should be around 1.1 volt, I cannot find the error! All other tests are good : the voltage between pin 2 and 1 is 9V and finally i have 9V between pin 20(-) and pin 40(+) of the socket of IC3 and 5V between pin1 and pin20 of IC3
