Here the ceramic vac tune and vac load caps are installed. Along with the 'L-Pi' network, which consists of a
C-L-C-L-C output network. The anode to grid C + the 1st inductance, form a step down L network. This transforms the
Plate load Z...down to a much lower Z, low enough, that a practical PI network can be used, with a normal loaded Q.
The 4 x plate block caps are also installed, along with the anode to plate choke connections.
