I must admit, having helped build a tube amp back-in-the-day, it is very add seeing a ICs in a tube amp ;-) Sure does help make it smaller though.

There were a LOT more then one tube in a tube amp back then.

The design here is more accurately a hybrid design I suppose. It is the phono amp in my second system. My main system has 10 tubes in the phono amp alone. However, the Bellari being an entry level unit, still sounds very good. I spend more time listening to it than I do the main system.

Sure that tube stuck in there isn't just a sales gimmick for people who think they ought to buy tube stuff? I mean it looks like the board is doing most of the work anyway.

Inside the good ones - is mostly air.

I am positive due to the fact that swapping different tubes has such a huge effect on the sound.

From the manufacturers website, until I get home anyway, a pic of the guts of the BAT VK-P10 Phono Stage with 10 tubes.

Very cool, I do not think I am talented enough to do that.

Hey Doc, have you ever seen the site iFixit? They document beautiful and detailed teardowns of electronics for the sake of repair, maintenance or just plain curiosity. It's fascinating stuff:
