A bit about JJ Electronic tubes:  JJ Electronic tubes are based in Europe - specifically in Cadca, Czech Republic.  Formed in 1993 after the Tesla brand went out of business and sold all of the patents, machining and inventory to JJ Electronic.  JJ Electronic tubes ARE NOT reproduction tubes, made in Russia or China.  They are authentic, European designed and manufactured tubes.  We (Antique Radio Salvage) are authorized importers and resellers of JJ Electronic tubes.  We stand behind these tubes, and can assist with any inquiries both pre and post sale.
From their website:
JJ Electronic is a world-renowned manufacturer of vacuum tubes, electrolytic capacitors and high-end audio amplifiers. Founded in 1993 by Jan Jurco, a small garage business grew to become a well known and respected in music industry.
JJ vacuum tubes and capacitors are widely used in guitar and audio amplifiers, recording studio equipment and in a variety of applications for audiophiles.

Our Testing Methodologies
JJ Electronic tests every tube before they leave the factory, but our testing doesn't end there.  We receive the tubes, in boxes, from the factory - and unbox and inspect each one for flaws.  We then burn in every tube individually!
Each tube is then tested for NOS Transconductance, shorts and emission leaks.  Any tube that fails these basic tests is returned to JJ.
But here is the difference with ARS...
We then test each tube for plate current.  While the GM (transconductance) on new tubes are well defined, plate current of the tubes can vary widely.  We measure the plate current (power draw on the tube) and record it on the inside of the box.  During this process, we are able to effectively match tubes - based on the most important matching factor for audio output tubes - the plate current.
When using these tubes in your amplifier, YOU WANT THESE TUBES TO BE MATCHED... not simply by GM, but by PLATE CURRENT for the most efficient, best sounding and highest operating conditions.  Don't settle for a random set of tubes... while they may be matched for transconductance - MAKE SURE THEY ARE MATCHED FOR PLATE CURRENT!
