Here's something I've been doing some thinking about....


Okay, in some Fender guitar amps, the components are mounted on eyelet boards that use vulcanized fiber board as the insulator, some amps, like early Marshalls, use Turret boards that use an insulator made from Phenolic, and some use Turret boards that use FR4 Fiberglass as the insulator, which got me thinking, is it at all possible to use 3mm MDF board as an alternative insulator material?, my biggest concern is how much voltage 3mm MDF board can withstand before there are voltage-leakages between turrets spaced 3/8 inch, or 10mm apart?
