Available in Platinum Matched Pairs, Quads, Sextet or even Octet Sets!!!

The platinum matching process consists of a 24 hour tube burn-in period followed by a bias (plate) current measurement in milliamps.

Whether it is the 6550C or the EL34, you cannot beat the reliability and quality of Svetlana power output tubes, that is why we only stock and use one brand.

I have found from selling hundreds of matched pairs that the Svetlana EL34's are the most indestructible and best sounding of all current EL34's. They just work well in everything and produce the smoothest and most liquid midrange. Dynamics are very wide with this tube and it's linear power profile gives a solid bottom end punch without being overtly sharp up top.
