My GAT was one of the first and after six or eight years is only on it's second or third set of tubes... I don't understand why others seem to be having difficulty with tubes. Maybe we should all resist tapping on tubes to see if they are noisy. Looks like they are upgrading the power supply and audio circuits to increase capacity and sound quality. Tube changes are about a quality supply of tubes providing good sound. So, no conspiracy to report. I'll bet that new NOS tube they are now using is plug and play in your GAT; will sound wonderful and last a good long time.
Happy new year...
Bob
