Triple 245v Valve Amplifier
The Triple two four five amp is powered by 3 X UX245 valves in a Parallel Single Ended configuration and driven by parallel twin triode 5691 RCA red base the rectifier is an old favorite U52 . Each of the 45's is set up with its own cathode bias and each coupled to the preamp tube via its own coupling Capacitor. With this configuration, we were able to achieve a whopping 5.6 watts RMS.
UX245 valves are known for their wonderful presentation of the mid-range. With three tubes it will even satisfy those who like weight on the bottom end and the top end is amazingly clean and natural.
