[Kenwood] Kenwood TS-530SP

[Richard Knoppow]

    Can't find original post. May have been answered. If no output check 
switch on the back for scree grid voltage. If turned off there will be 
no output or indication of plate current. Switch is there for 
neutralizing finals. Normal position is on.
