Proud Members of the California Historical Radio Society______________________________________________________________________________________________General Info: Please read the listing in its entirety to understand what you are purchasing.If any information is unclear, its better to ask questions now than to have a return. JNS Vintage Radios and Tubes aims to be as accurate as possible when describing and testing radios and tubes. However, we are not experts in all Antique/Vintage Radios, Electronic Equipment and Vacuum Tubes. If you see an error, please contact us thru the eBay messaging system so we may correct the listing. Our vacuum tubes are inspected and tested on our newly rebuilt/calibrated Hickok 539B tester. The 539B is one of the best Hickok Testers. Each tube is cleaned and allowed to warm-up for 90 seconds prior to actual testing. Tubes are tested for quality, life, grid emissions and shorts. No tube is offered for sale that tests below the min number given. We also use our Triplett 3413B as a backup tester. Please note that all tube testers are not created equal, and your tester may show a higher or lower test result than our test equipment. All tubes are wrapped in bubble wrap, packed with peanuts and shipped in a sturdy cardboard box to protect it during transit. All antique and vintage radios are cleaned and tested when possible. Well provide an accurate description of the condition within the listing based on our findings. If you find an error or omission, please send us a message thru eBays message system. We now offer restored/repaired chassis by Bob Kelly Radio Restorations here in the Sierra. Bob has over 45 years as an electronics technician in the communications industry and has provided quality radio restorations for many years. Radios are wrapped in bubble wrap and packed with peanuts and when necessary, squares of Styrofoam used to protect glass dials, knobs and switches.
