EL34 Siemens (6CA7)
Slightlly used, tested like new, in original boxes, Siemens actualy never made any EL34 / 6CA7 in their plants. Ring getter and two slots in plates. I'm not sure if they are from Philips Mullard Blackburn factory or East Germany RFT production. Anyway very good sounding tubes comparing to current production, with good bass and balanced mids, good choice for guitar amplifiers.
