NOS Sylvania VT-25 10Y tubes. Made in WWII these Sylvania 10Y are excellent for Audio Note monoblock amplifiers like the Audio Note Kegon, Gaku-On, Baransu, Kageki balanced and other high end amplifiers! I had the opportunity to roll many pairs through a set of Audio Note Kegon monoblock amplifiers and we discovered the perfect range of current (mA)draw which resulted in the widest open sound stage! These are an excellent investment for your system. All pieces are thoroughly tested, matched, and screened on our Amplitrex AT-1000 testing system, and then additionally tested for gas, shorts, leakage, and transconductance on our computerized and calibrated Hickok 118B. If you are an Audio Note monoblock amp owner, please let us know and we will provide pairs within the sweet spot range! We got in over 300 pieces of these extremely rare tubes so we can provide the tightest matching available in the world! Supplied in either military boxes or white boxes.
