(2) Vintage Telefunken 6CA7/EL34 power tubes in excellent condition. These appear to be RFT tubes with the dimple tops, likely manufactured in the 1970s. Both test very strong/NOS on my B&K 707 tube tester. Here are the results for mutual conductance with 65 being a good tube & 90+ being NOS; 96, 95. Great tubes for your vintage amplifier or hi-fi needs!
