Dyna ST-35 / Tube Glow

Tubes Asylum

Questions about tubes and gear that glows. FAQ

Hi, I noticed when playing my Dyna ST-35 amp in a dark room that the 2 front power tubes ,one on each channel were not lighting up as bright as the same power tube behind it, on each channel. Even with my hand on the cage as a heat test, the rear power tubes, one on each channel seemed hotter. The amp sounds great and I can't hear any problem. Has anyone ever noticed this and is it something to jump on quick before something fails? It's always been like this for quite a while and I'm finally asking this question because else wise it's been working and sounding perfect.......thanks for any advise......Mark Korda

Take Rod's advice and swap the tube, bright to dim. - Ivan303 09:05:02 12/07/23 (0)
