[Johnson] Ranger CW chirp

[C E]

Double check the OA2 and 6AU6 tubes in the VFO. You
might as well check that 18k resistor while your at it
(just in case it decided to increase in R after all
these years). Be sure to check the power supply too. I
put a stiff 100 uF 450 VDC cap on the l.v. power
supply.
