[Johnson] Ranger 1 with no grid current

The Ranger has been through many "helpful" hands.  It would be a good idea
to trace out all the wiring (yeah, it is a pain because of the cables).

I found a lot of interesting "mods" when I restored a Ranger 1.

A good place to start is with a bath in warm soapy water (the radio, that 
is), a rinse in distilled water and a two or three day dry in the sun.

In the restoration process I replaced all the capacitors, meter resistors 
and anything that was slightly suspicious.
After all that work I discovered that the silver micas in the VFO were leaky 
and unstable.

I found the problem.
R5 (68K ohm) resistor was bad(open), replaced it and now the Ranger seems to 
be working fine. Using a dummy load I can hear my CW and phone signals from 
another radio in the same room. I have no idea how much output I have. I 
need to hook it up to a watt meter.

One problem I am having is that the OSC meter is peging hard to the right.
I have checked the 3 ohm SH1 resistor and it checks out at 3.5 ohms.
All of the voltages for the 6CL6 check out fine. I get negative voltage on 
pins 2 and 9 and the screen voltage is 99 volts.

Any ideas?

Thanks,
