“All four tubes were matched within 1 mvolt when I installed them in my vintage Jolida integrated amp. Awsome! Had to adjust bias down on each by a couple volts. Initially sound was A bit sterile but after about 20 hours the sound is more spacious. Very happy so far ... will purchase additional tubes from Upscale!”

“Still putting hours on these new EL34's So far they are not as crispy as the set of KT77's were. A little brighter than the 2022 Mullard EL34's They sound just about right in my old VTL Compact 100's”

“I replaced the KT88 tubes with the EL34 in my Prima Luna and was quite pleased with the sound. The service was very fast and the tubes arrived in very good packing.”
