A few questions. What kind of tubes are in your preamp? How many tubes are in your preamp? How long have those tubes been in the preamp? And how old is the preamp?
Do I need new tubes?
Until recently, when I turned on my rig it immediately sounded full bodied and rich. In the last few weeks I’ve noticed it doesn’t reach this state immediately, but rather until at least after an hour. From then on it’s fine.
Is this a sign my preamp tubes are aging? My amp is solid state and always on.

I have the same tubes in my preamp as well and they should last a minimum of 5000 hours. Depending on how they are configured, maybe as much as 10,000 hours. Oh and I have used the RCA Cleartops @dogearedaudio mentioned and they are great and not that expensive. Bought a matched pair from Brent Jesse for I believe $100. All the best. |
