Hi, Apologies if this is not the correct place. I would like to ask advice for any repair shops you may know that may be willing to repair tube amplifiers. Ideally in South/Central Europe.

Hi, Have been reading a lot about these tubes, but not much in how they would work in combination. I am thinking of commissioning a headphone amp with the above tubes. Can anybody advise me on the best tube combinations from the above if anybody has them? I mainly listen to Jazz Instrumental...
