Hi Paul,
you can - but not recommended. Valves generate a lot of heat, and PCB
is not good at dissipating it - would have problems very soon. Why not
use aluminium sheet - easy to work as PCB, - I get mine form a local
scrap merchant, they have pieces big enuff to build any chassis I want,
and its a lot stronger AND cheaper than pcb.
