Lots of tubes in this beauty. The tall silver object to the left is a cap can but to the right is an 6CG7, three shielded 12AX7’s and another 6CG7.
Why didn’t all amp manufacturers print the tube requirements directly on the chassis like this?
Output tube and phase inverter sockets.
Sylvania made 6GC7, RCA made 6L6 and Phillips made 12AX7/ECC83 tubes. Simply beautiful.
