NOS 'Siemens' EL34 (Singles, NO MATCHED PAIRS)
Labeled and boxed as Ruby Tubes.
East German EL34s (manufactured by RFT) with great tone. Last of the reasonably priced NOS EL34s. 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 sound great in my 65 amps Producer. had a pair of Svetlanta winged =C= in there, and they were really good, but the Siemens have less sag in the lower register, more headroom, less upper mid spike, and more transparent and balanced frequency response in general. The distortion is super creamy and articulate.
Thanks, Steve Kirk
"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"
Hi Mike, I received the rft Siemens el34 quad a few days ago and I tried them out over the past few days. The sound is superior to any other tone I have come across. The clarity and reaction time to the tubes from the strings is great. Very articulate. In end, they rock. Thanks Sandip
