Hi guys, my J5 suddenly stopped working after a couple of months: I checked the fuse and it's showing no continuity.
Before blowing the only replacement fuse I have at the moment I wanted to take some measurements.
The power transformer used to get quite hot after an hour of use, so that's the first suspect.
I could still keep my hand on the top surface without burning myself, but it sure was uncomfortable. (Is it supposed to run that hot?)
This is what I measured.
Primary (pins 3-7): 38.6 ohms
Heater (pins 16-18): 1.0 ohm (unsoldered leads)
HT secondary (pins 10-12): 100.4 ohms (leads still on, standby switch open)
Shorted test leads: 0.9 ohms
How do these ones look?
