Does anyone have a lead on the availability of R35, that 20kohm 50 watt voltage divider/bleeder resistor used in the modulator circuit of the Ranger I/II transmitters? 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.
