From the “trusted” sources (whatever it worth) I heard very positive comments about the pre-2004 production compare to the vintage tubes. There is however a twist in it that I hope you will explore as it is very much your subject. The contemporary productions DHT tubes (Russian of Chinese) are superbly firm and have no internal noise when they shacked or hit. The mintage 60 years old tubes what you make the “close to ears” test responses like as somebody threw a bicycle from a roof of Empire State Building to the ground. However, the vintage tubes are not necessary all that rattling project to sound? So, since you have a long experience to correlate the shakable and auditable then I hope you will explore it further.
