I recommend sending your amp to ARC for tube replacement. They will match the tubes appropriately and make necessary adjustments. Your amp will return sounding the way it is supposed to sound. Sending your amp to ARC for tube replacement will cost more, but it will be worth it in the long run.
Audio Research VT100 tube replacement
Hi everyone, I am new to tube amps and I need to re-tube this amp. I have discovered that some music lovers prefer the sound of NOS tubes over the ones Audio Research sells. I will have my Audio Research dealer bias the amp when I purchase the new tubes. My question is what tubes would some of you with more experience suggest. My musical tastes include pop, rock, dance and some classical. I do enjoy listening at moderate to higher volumes most of the time (don't know if that helps in choosing tubes). My preference would be for smooth sounding highs and mids with punchy bass, my ears are sensitive to higher frequencies and I find that I get listener fatigue very easily from a lot of different solid state and certain metal dome tweeters. Any suggestions would be much appreciated, also any tube retailers that you have had good experience with would be great. Thanks to all and happy holidays
