I think the simple 45 with Magnequest output transformer is a great place to start and a very simple project for the builder. I would use a K & K CCS on the first tube and a Magnequest DS 050 for the output transformer. The first tube can be any of the 12AT7/12AV7/6N1P varients (like the 5965). Don't forget that with 2V coming from the CD player or phono stage and a bias voltage of -56V you only need a gain of 28 to drive the amp to clipping. If we add 3dB for headroom, you still only need a gain of <40 to drive the amp to clipping. That's not much of a challenge.Don't get bogged down in audio dogma. Keep it simple and worry about boutique parts later. Those are things you can change or experiment with yourself once the amp in built. If you start with an excellent output transformer and a chassis with plenty of space, you can mess with it for years.
