NOS Siemens Telefunken RFT EL34- Regardless of the branding (Siemens Telefunken Marshall RCA CEI Westinghouse STC, the list goes on and on), these German made EL34 are simply awesome and were standard equipment in many Marshall guitar amps in the 70's and 80's! Perfect for hifi or guitar amplifiers,,,superb dynamic range and far surpasses any current production EL34! We were able to get over 100 pcs from a supplier so we currently have in stock National, STC, Westinghouse, and unbranded available but all are genuine RFT made EL34. Because of our large supply can provide identical current (less than .5 mA apart) matched pairs or quads!
