Re: SX-122 Calibration Questions
开云体育John, good to hear about your find. I am just trying to understand your situation, but I am a poor reader SO.. The 50kC? thru to the speaker works well ? The 1650 thru to speaker is not good .. weak output or noise, but works ?so something is not right in the 1650 despite attempting alignment? RE “But, as I said, the set is working” ?????means stations received ? What all do you have to test with? From: [email protected] [mailto:[email protected]] On Behalf Of John Limbach, K8NN

Recently purchased an SX-122 in great condition.? ?Less cosmetic wear than you'd expect from an early '60s radio.? No mods or changes underneath and very clean there as well.? A few tubes had been changed but several still had the Hallicrafters markings.? Five of the tubes tested below acceptable level on my calibrated Hickok 539, so replaced them with NOS tubes that tested to spec.? The set performed well on my very short length wire that starts on the workbench in the basement and makes it's way up to the roof on the deck. ???????????++++++++++++ -- don??? va3drl |
