Brown bases, made in Holland. Various markings including Amperex, CBS etc. Sorry, no matched pairs.
Same tubes as the pre 2001 Svetlanas, made in St. Petersburg Russia, but branded SED. These are the real deal. If you see "Svetlanas" for less, they may be ones from the Reflector factory which are not of the same quality level.
Standard matching within 3mA.
Some labeled Siemens, others AEG.
East German EL34s with great tone. Last of the reasonably priced NOS EL34s. Great original boxes. Not recommended in amps with plate voltage over 450 volts though many cases of success at up to 500 volts have been reported. Bottle has dimple in the glass on top. 4 staples in the plates.
"Mike: These are SO much better sounding than the JJ E34Ls in my JCM800, I can't believe the difference. I'd like 2 more pairs to match the first pair. Thanks. Lee Bridenstine"
