[Johnson] Ranger mod screen resistor, R35 needed.

[Gary Schafer]

To get you by you can put a small cable clamp over the burned spot in the resistor to short out the open. The total resistance will be a little less but it will work. Use a clamp that looks like the variable tap for the resistor but without the little depression that makes a small point contact. You want a little wider contact to ensure that several turns get shorted.

I discovered (to my woe) that I couldn't do AM last night. I troubleshot the problem and found I couldn't adjust the resting screen grids of the 7027's to the 55-70 mA range called for by the manual. Sho' 'nuff, I traced it to a faulty R35. Now the question: where can I get one and how much do these puppies run? Enquiring minds want to know. Cal, N6KYR.
