Type 45 Matched Pair Raytheon Tubes Strong Testing #45 TV7 Test

This strong-testing matched pair Raytheon Type 45 ST glass tubes was tested on our TV-7/U and measurements are:


Tube One: 62 / 86% (Raytheon stenciled on base with code F8; 45 stenciled on glass with an original retail label still affixed)

Tube Two:  59 / 82% (Raytheon stenciled on base with code I10)


Tested on our TV-7/U where new / nominal is 72 and minimum (65%) is 47.  Tubes have bottom D foil dimple getters. Tubes have some minor bonding cement debris in their bases but this does not affect their performance.  Sound tested on our Alan Eaton amp and they sound great - see pics.


I have a number of matched pairs of Type 45s in my Reverb listings, please view to see if any fit your equipment needs.
