Not sure the tubes are the problem. Sit tight and see what else might be the problem. Tubes generally last a very long time.
Need help choosing replacement tubes for my 211 SET
I have a Voxativ 211 Integrated Amp. It came with Psvane tubes and they are beginning to wear out, or at least I believe they are since the highs are starting to sound poor. A few questions, do I replace all the tubes including the driver and input stages? Is that standard practice? Finally, what are some good recommendations on replacement tubes for the best sound? Budget is around $500 but can be stretched somewhat for something significantly better.
