If there are tubes in there, I can't see them.  I do see the huge cans, heat sinks and output transistors.  Is the pre tubes and the power am SS?

The tubes are laying horizontally in two stacked pairs just in front of the big blue caps.   The socket is almost easier to spot than the tubes.

Sir Thrift-a-Lot:
Or is that behind the big blue caps?

looks to be a vacuum tube input stage (pair of 12AX7s per side) and solid state output stage.  Nick - if it has 12AU7s in there now you may notice a nice improvement in gain with the as-designed 12ax7s (gain = 100 vs gain=17 for the AUs).

wood panels look cool!

Spotted the sockets and then the tubes
