Once purchased and received by Platinum Tubes, vacuum tubes undergo exacting quality control measures to further assure reliable, sonically acceptable performance. Each power tube is then tested and graded for technical characteristics specified by platinum tubes engineers. Only after a tube successfully passes these exacting challenges is it labeled and put into stock to be sold. Tubes not meeting these criteria are rejected to the supplier or disposed of.

 Average tube life will depend on several parameters: product type, how the product is installed, loudspeaker efficiency, room size and acoustic damping, listening habits or average sound pressure levels, A.C. line stability and purity, and other circumstances. Generally, preamplifier tubes last up to 5,000 hours, while power amplifier output tubes will last up to 3,000 hours. Near the end of their useful sonic life, aging vacuum tubes may degrade the sonic character of the product(s) they are used in. The sound may become somewhat dry and lifeless, with a noticeable decrease in harmonic richness or bloom. Bass response may be diminished, and musical dynamics may flatten out or compress. Toward the very end of their service life, tubes may become noisy, noticeable as a slight rushing sound or rustling noise. It is far better to replace vacuum tubes prior to the end of their service life, before severe sonic degradation or outright failure occurs. Running vacuum tubes into failure may damage to other internal components and cause needless repair expense.

Factors which can shorten tube life include inadequate ventilation, overdriving loudspeakers at continuously high volume levels, severely fluctuating A.C. line conditions (e.g. sagging line voltage during summer peaks of air-conditioning demand), or severe interference pulses or electromagnetic interference.

*In the event of a failure, tube(s) must be sent back to us at the buyer's expense. We will expedite any replacements after testing the tube internally at our expense.
