After many years of light use, I decided to replace the original EL84's Groove Tubes in my Fender Blues Junior Tweed by these matched pair of Sovteks. I think these are the cheapest or one of the cheapest EL84 pairs I've found at Thomman, but I was not disappointed in any way. I could not notice much of a difference in sound at low bedroom levels, which I did not necessarily want/expect. Nevertheless, I feel more confident taking the amp to gigs now and I kept the old original tubes as spares.
Order processing by Thomann and delivery were fast as usual, and the tubes were super secure and arrived intact. I can definitely recommend this product.
