Hey big hair guy…the only person on planet earth whose hair is visible from space. You must also consider the driver tubes to be used with the power tubes and also the phones you will use and your personal preferences. Personally, in terms of encyclopaedic levels of knowledge, I’d pm @Doug2507 in the land of the Haggis and ask him for recommended pairings of driver and power tubes. You’re very welcome and the invoice for my consultancy services is already in the postal network.
