Well I don't want to be the first to criticize this, but the tube output stage does raise some questions.
They appear to be the Svetlana SV-572. That tube went out of production ten or fifteen years ago, and I don't think they will ever be made again. You used to could find them on eBay. They are a mechanically fragile tube. That is, they don't travel long distances well. Something to think about as you try to stockpile a reserve of tubes.
The only info I could find about how they are used in this player is that they are used as a linestage. I don't know why they chose a power triode for linestage work. The 572 is damn near a transmitting tube. Those thoriated tungsten filaments sure do look cool though don't they?
