Depending on how long its been since you've changed tubes or purchased as a used tube unit...I would do it right and buy a whole new set and keep what you have for back up tubes..Create a log on when you installed the tubes and roughly the hours per week you usually use your system.This will give you a better handle on when the next time comes around you need to figure out if and what tubes you might need to replace..if you get 1500-2000 hours on them you know its time reach in the pockets.................Its just something I do to get a rough idea on when to change tubes...
Funny sound from tube setup
Looking for some sage advice on how to find out what tube needs replaced in my tube amp/pre setup. What tubes do you start with?
I checked my bias on the KT 88's and they were spot on, I imagine this means these are ok. One of my other amp tubes has what appears to be a black top instead of a silver top. Never looked that close at the tubes until now so I'm not sure if it just like that. What should I try next?
