Hi folks,
It maybe that the IP-17 is just like that or it's malfunctioning, not really sure. I noticed that when both the C- & B+ voltage knobs are at min and the DC switch is turned ON it rises to like 25V and then slowly drops back to 0V in a few seconds.
So, now if I switch back to STANDBY then the voltage quickly goes to like -14V then rises back to 47V and then slowly drops back to 0V.
Is this a common phenomenon with the IP-17 or something is going bad inside?
Here is a video of the issue I have shot an posted for better understanding. I have a feeling it could be the caps that are discharging slowly?
In the first part I've used a load resistor to see if it is able to absorb the voltage fluctuation.
Also I found the same issue on another video posted by another person sometime ago but on an IP-2717A, timing from 3:43 to 4:24 to see the issue:
