I would reflow some of those solder joints, they look a little flakey. 

115 ohms sounds OK.
 Your are measuring one half of R58.
 What is the reading across both halves together of R58? 

120 volts sounds way too high for R58.  That would make some 900+ MA  That would make way too much current. 120v would pop C59.
 It sounds like it's intermittent open.

Even if it's 100 MA would be only 12.8v

I am not familiar with this radio. With push pull output the current will be on the high side.

Stick some making tape on the components with there circuit numbers. It helps me. Again I am not  familiar with this radio.

Oh and it's helpful when soldering to turn the caps so you can read the values on them.
