Quad Of Vintage Tesla Roznov EL34/6CA7 Tubes, Brown Base, Double O Getters

[Rudes]

Here is a quad (4) closely matched vintage Tesla Roznov brown base EL34/6CA7 tubes that have the Dynaco name stenciled on them. These were manufactured in the late 60's early 70's. Excellent flashing and test very strong. Double halo getter. Where a new Electro-Harmonix EL34 test at 5000 micromhos, two of these test at 5400 micromhos and two test at 5600 on my calibrated Hickok tester.

Same tubes used in late 1960's and early 70's Marshall amps.

$250 for the quad
