[Johnson] Ranger 1

[Jim Brannigan]

Which caps?
Which plate voltage (HV or LV)?
Have you taken any measurements?
Trouble shooting is a logical process.  Break the problem down.  Start at
the power supply and measure the voltages.
Move on from there as your measurements dictate.

> I have a Ranger one that was working fine until I decided to replace a
couple of caps. It still seems to work fine but I now do not have any plate
voltage (when the mode switch is turned to phone or CW with the key down).
I checked the clamper tube, the power transformer and most the other
tubes...all fine. The electrolytics are also fine. I believe the wiring is
OK. Where should I start looking?  I'm not the world's best tech...but I do
have a very healthy respect for the high voltages in this unit.
