Changing tubes should not cause clicks, pops or hissing. If the socket is loose, get it replaced or repaired ASAP. And if the tube is what is loose @jetter give perfect advice.
Wiggle kt170 base
Hello everyone,
The sound on my tube amp was pretty good with the kt170. But I made a mistake. I took out the 4 kt170s and put in kt120 to understand the differences more. Next day I put back the the kt170 each into their exact slot from before.
There is hissing on the right speaker and a rare medium pop now. The very left kt170 has a very slightly loose base. Does this affect sound? I have no more intention of removing the kt170s if the loose base doesn't affect sound I'm fine to leave as is.
Could you teach me more about this hissy sound? I didn't touch any of the pre-amp tubes and they are all mostly nos. The hiss is softer today than it was yesterday.
