After estimate placement too many components so I decide to build mono mono amp.
Drill holes for mount component.
Rectifier tub is 5U4G.
Signal driving tub 6C45pi.
Amp tub VT4c-211.
High voltage for 211 plate voltage I usage C-L-C balance circuit .
Two chocks one is for 211 B+ another for GND.
Top side picture.
Left corner is OPT.
Right corner is High voltage transformer and heater transformer.
C-L-C High voltage I cascade 3 capacitors for 1800V (no Tub insert).
High voltage I usage 2 times frequency boost to 1600V.
