Sovtek 6N23P-EV / 6H23P-EB NOS for AI Modulus 3A?


I need to replace the tubes of my Audible Illusions Modulus 3A phono stage. As I live in Europe I prefer to order them here from Tube Amp Doctor (TAD). TAD recommends their own TAD 6922 / E88CC Premium Selected or Sovtek 6N23P-EV / 6H23P-EB NOS.

Has anyone experience with Sovtek 6N23P-EV / 6H23P-EB NOS? Are these similar to the 6H23n-EB/6922 ones The Tube Store or Upscale Audio recommends?

Thanks much for your input

If you are right then it would mean that the tubes of the phono stage need to be replaced anyway. But it could be a cap too. Difficulty is that as far as I know AI has no distribution network in Europe anymore
Perhaps a local technician could diagnose your problem and fix it. You don't always need the manufacturer to repair thier products, although some times it does help if you can do so. Check around and find a recommended repair agency in your country, one that has experience working with tube products. Call and ask what they can do if not local.
