Hi everyone, I¡¯m starting with oscilloscopes and electronics. I got a Tektronix 475 that I would like to repair for my lab. It turns on but unfortunately I have no trace...I tested the voltages. Everything seems to be ok (+15v, +8v , +115v) except for the 50v, I get +65v...all components in this sector tend to heat up after 10 minutes. For the rest, I do not know where to start? Thanks in advance for your help, PS
