Don't forget the 753 hour break-in period (heh…). I can sympathize regarding sonic attributes of tube swaps as the differences are obviously subjective and often subtle. After all, it's the same amp…I can say that the 150s in my 502 have stayed absolutely static (no sonic degradation I can hear) over thousands of hours, and I rarely adjust the bias (generally only when it "seems" unbalanced, but this likely has more to do with the unstable electricity in my house, and my propensity to fiddle and burn my fingers). I expect thousands of hours more from these tubes as my 120s lasted longer than I expected anyway…we shall see…Also, I wonder why they don't produce a gold pin version of these things.
should i go with kt150's now or wait a bit??
simple question folk's, I have two jolida 502 amps running in mono. kt120 tube's with about 200 hours. just broken in lets say. this is almost going on two years now so I guess Im not listening as much as I should be. I will take care of that!! the amps are running the top end of my infinity 1b speaker panel's. mid's and high's. no bass work here. so the question is is it worth installing kt150's at this point in time. for $600, I would need eight of them, what kind of improvement in sound would I get. with just 200 hrs on 120's would you run them a little longer to at least get some use out of them. everybody like's the 150's for the solid bass they get out of them but I would not see that running the mid/tweeter panel. what would you guy's do if you had the $600 ready to go?? (don't answer that) can we assume in time the 150's price will drop a little more and just wait it out . I know it's such a tough decision here, just help me out ok. thanks
