Quality
All Russian tubes and parts satisfy Russian State Standard requirements.
Russian State Standard regulates quality assurance, calibration of
measurements, technical conditions of manufacture and operation. Their
requirements are specified on the data sheet. Russian vacuum tubes have a
worldwide reputation for being extremely reliable and unique. Tubes are
checked prior to shipping. We do not sell used tubes. We sell only new tubes
or NOS (new - old stock), except for collectable rare tubes.
A lot of Russian tubes are exact analogues of Western and American tubes.
Please e-mail your request specifications and we will give you the Russian
analogue at a price lower than that of its Western counterpart. See the tube
data sheets on this web site to choose your appropriate Russian analogue.
Russian tubes are very popular worldwide, because they have the longest
operating lives. High quality of Russian tubes is achieved by a high temperature bake-out of ceramic than in the West. Ņeramic doped with chromium, molybdenum and aluminum ensures exelent metal-to-ceramic brazing bond.
Please inform us about the quality of the tubes. |
