Leaky Tubes / Valves Can Blow the HT Fuse In Guitar Amps, TubeSync Can Avoid This!

Thursday, July 1st, 2010

An interesting phenomenon that some ‘leaky’ tubes, removed from conventionally biased amps, appear to improve when run with TubeSync. The reason may be that when the tube gets hot, g1/cathode leak causes a current increase, but it is automatically biased ‘back’ to compensate, which allows the tube to cool down again and thus reduce leakage et al. After a while the leak sometimes reduces or disappears completely – we surmise that the getter  gets a chance to mop up stray gas molecules or the metallic deposit gets ‘boiled off’ the mica supports.  This type of fault in a conventional amp would normally blow the HT fuse, however TubeSync can avoid is and rectify the problem! Cool eh?
