|PRIMO TUBE SETS|
We search the world over for vacuum tubes sets which we classify as PRIMO. They are value-priced (they don’t cost a small fortune) and make you and your amp sound great.
We choose many tubes from the 1940’s to the present. Some tubes may have been hidden away for years in old warehouses, military bunkers, storage sheds or grandpa’s attic and some may be bulk purchases from current production (EHX, JJ, Sovtek, Svetlana, Mullard Reissue, Tung Sol, etc). They come from Russia, Europe, Asia, and the good ole USA. Recent great finds include Russian military (1960’s to 1980’s usually including 6V6/6N6C, 6L6GC/5881 equivalents, and 6BQ5/EL84/6P14P equivalents, etc). When they get into our tube lab, they are quality tested on Hickok 539B or 580 or Maxi-Matcher® tube testers for gain, life test, shorts and physical appearance. MATCHED TUBE SETS are matched first for manufacturer (tube code, not label) and then for gain/current draw.
We often get tubes that are decades old it and it is hard to determine if they are New in the Box (NIB), New Old Stock (NOS), bulk lots sold without boxes, or replacement tubes with great life still left in them. Our extensive experience and comprehensive testing means we throw out a lot of old and new tubes if they test below minimum “NEW” reading on our calibrated tube testers or they don’t pass the LIFE TEST. You can be assured that all the tubes we sell are tested to new or better according to manufacturer standards.
We don’t specify the specific brands sold in PRIMO Tube sets for any particular auction since we want to give you the BEST VALUE for the price. We do have general brand guidelines we try to follow when inventory is available for specific tubes numbers and these brands are shown in the table below. With over 7,500 satisfied customers on EBAY, our quality control, selection criteria and value pricing have proven results, so we are confident that you will be pleased with your purchase.
For customers who want specific tube brands, these are often available as individual or matching tube sets.

PRIMO Tube sets usually DO NOT INCLUDE manufacturers such as Genalex, Telefunken, Mullard, Phillips, Valco and other high priced tubes.
In order to offer the best prices for our customers, we may substitute high quality equivalent tubes. Check Store pages to see a cross reference table of equivalent tubes that are equal or better in performance than the original tubes.
NOTE: WE HAVE MANY SETS OF THESE TUBES AND THE ONES YOU RECEIVE MAY NOT BE IN THE SAME BOXES OR BE THE SAME MANUFACTURERS AS ILLUSTRATED IN THE AUCTION PICTURE, BUT THEY HAVE ALL BEEN TESTED TO THE HIGHEST STANDARDS ON OUR TUBE TESTER. EQUIVALENT PERFORMANCE RESULTS IN YOUR TUBE TESTER OR IN YOUR AMPLIFIER CANNOT BE GUARANTEED DUE TO VARIATIONS IN EQUIPMENT AND CALIBRATION BEYOND OUR CONTROL. WE USE PROCOMM, EI AND WESTINGHOUSE TUBE BOXES FOR ILLUSTRATION OF THE TUBES IN AN AUCTION TUBE SET ONLY!
