【Product Description】 PSVANE EL34 C, set of 4, in excellent condition. These were removed from a brand new Triode push-pull amplifier that was in working order, due to a vacuum tube upgrade, so their characteristics are all matched. Actual usage period was about 3 weeks. I believe they still have plenty of life left. 【Included Items】 Main unit only, no original box. * Please double-check the product description and detailed images.
